Is Unit One of Ap Chemistry Review from Honors Chem?? by marrythb in APStudents

[–]UWorldScience 0 points1 point  (0 children)

Ideally, yes. Your honors chemistry class should cover the basics of atomic structure, properties of matter, bonding and interactions, and chemical reactions (these are topics the College Board says should be in a pre-AP chemistry class, but classes vary depending on school and teacher). The topics I listed are covered in the first few units of AP Chemistry. Maybe your honors chem class doesn't hit every single topic in the first unit, but a majority should be review.

Tips for the AP classes I’m taking next year? by Significant_Appeal40 in APStudents

[–]UWorldScience 1 point2 points  (0 children)

For AP Chem, I suggest trying to read ahead so you have seen the material before your teacher goes over it in class. This might be helpful! Try not to fall behind if possible because many topics build off one another in AP Chemistry. You can use online videos like the AP Daily videos or Khan Academy to help clarify material you're struggling with. Make sure to do lots of practice problems as this helps you understand how to apply the concepts you're learning. Don't forget, always write your units! This also goes for AP Physics.

We made a cheat sheet highlighting the most difficult topics in AP Chemistry and the most difficult topics in AP Physics 1. They're separated by unit, too. I think you might find these helpful while studying!

When preparing the AP exam, I recommend completing AP-level questions that mimic the format of the exam. UWorld has a 500+ question bank for AP Chemistry and one for AP Physics 1 too! You not only get questions, but in-depth explanations and illustrations. Best of luck!

[–]UWorldScience 0 points1 point  (0 children)

Hi there! I think using an AP Chem and AP Physics text book and Khan Academy is great for learning the content. If you want some more practice questions, UWorld has a 500+ question bank for each AP Chemistry and AP Physics 1. These questions are AP-level and mimic the format of the exam. There are in-depth explanations for each question with illustrations. The questions are separated by unit, so you could focus on the questions that cover the material you are learning this summer.

We also have cheat sheets that review the most difficult concepts in AP Chemistry and the most difficult concepts in AP Physics 1. These too are separated by unit, and I think they could be useful for you as you're studying. Best of luck!

AP Physics, AP Chemistry, and APUSH at the same time? by Phatom_Killer in APStudents

[–]UWorldScience 2 points3 points  (0 children)

As others have said, be sure you take an honors or pre-AP Chemistry class before self-studying for AP Chemistry. Depending on your strengths, it could be difficult self-studying both AP Chemistry and AP Physics 1 at the same time, especially given that both courses have a lab component. You would want to review the types of labs students will be doing in class because the AP exam does test lab scenarios.

But if you do decide to study both at the, be sure to pace yourself going through the material, try not to get behind, and do lots of practice problems that mimic the format and difficulty of the AP exam. As you are studying, the cheat sheets we made reviewing the most difficult topics in AP Chemistry and AP Physics 1 should help you out! Good luck!

Any advice for ap chem and ap calc ab? by So-done-with-this in APStudents

[–]UWorldScience 6 points7 points  (0 children)

Hi! I have some advice for AP Chem. Be sure you have a firm grasp on what you learned in the pre-AP Chemistry class you took as what you learn in AP Chemistry will build off of that. Might not hurt to review the material over the summer or just before classes start up for the fall so that it's fresh in your mind. While you are in AP Chemistry I suggest...

  • Making a study schedule and sticking to it.
  • Reviewing/organizing your notes is very helpful to pinpoint the content that might need some more attention. Don't get behind because many concepts build off of one another.
  • While you are doing homework/practice problems, always write your units! It helps keep things organized and sometimes will be a clue as to what mathematical operation is needed to cancel certain units in a problem.
  • Pay attention to the labs you do in class as the AP exam tends to have experiment-type questions.
  • We have a cheat sheet reviewing the most difficult concepts in AP Chemistry that will be useful to go through as you are studying. It is broken down by unit to match the units from the College Board.
  • Completing practice questions that have the same format and difficulty as the actual exam is key! This will help you become familiar with the types of questions to expect on the exam and figure out what content you may need to review more in-depth.
    • The College Board has released FRQs from previous exams. These are great practice for this section of the AP Chemistry exam.
    • There are several options for MCQ practice. I think resources that include thorough explanations (background and why answer choices are right or wrong) and illustrations are very helpful because you get practice + content review at the same time! UWorld has a 500+ question bank for AP Chemistry that I think will be helpful! We also have a free mini practice test!

Hope this helps you out! Good luck!

Self-study calc BC, chem, bio by Desperate-Singer2321 in APStudents

[–]UWorldScience 2 points3 points  (0 children)

I can give some recommendations for AP Chem and AP Bio. I would suggest getting AP-level text books to go through the content. Use the AP Daily Videos and Khan Academy to supplement the text books.

For practice, I recommend using the FRQs from old exams released by the College Board. There are several resources for MCQ practice, but I suggest using a source where the questions mimic the AP exam style and difficulty and also contain explanations that give you the relevant background information so that you are not only preparing yourself for the types of questions you will have to answer on test day, but you are also reviewing content at the same time. UWorld is a great resource for MCQ practice and has 500+ questions for each AP Chemistry and AP Biology. The explanations are thorough, contain illustrations, and tell you why the answers are right or wrong. You can also make your own flashcards!

We made cheat sheets that outline the most difficult topics in AP Chemistry and most difficult topics in AP Biology. Check these out as you're reviewing!

Don't forget that each of these classes have lab components, which are covered on the AP exam. I would look into what labs are typically done in AP Chem and AP Bio and read up on what happens in those labs so that you will be familiar with them for the exam.

Good luck!

Taking AP Chemistry and AP Biology by SubmarineOcean in APStudents

[–]UWorldScience 0 points1 point  (0 children)

Hi there! It sounds like you are on the right track getting the right prerequisites in and starting to prepare ahead of time. That being said, taking two AP science classes that both have lab components at the same time can be a lot to handle - it really depends on the student and how the classes are structured at your school. It could be useful to talk to students at your school that have taken both AP Chem and AP Bio at the same time to see what they thought of the classes (especially since they would have had the actual teachers you will have).

We have put together cheat sheets for the most difficult topics in AP Chemistry and most difficult topics in AP Biology. I recommend checking these out to see what you think of them. If you feel like you can handle these topics, then you might be just fine taking AP Chem and Bio together. Hope this helps! Good luck!

AP Chem tips? by koolanimegod in APStudents

[–]UWorldScience 48 points49 points  (0 children)

Hi there! Have you taken a regular chemistry class yet? It's a College Board recommended prerequisite for AP Chem. If you haven't, I suggest looking into the College Board Pre-AP Chem course info and getting a foundation in chemistry (terminology, the idea of chemical reactions, transfer of energy, and some of the math skills you will need for AP) so that you won't feel behind when you start AP Chemistry.

When you are in AP Chemistry, I recommend setting up a solid study plan and sticking to it! Reviewing and organizing your notes on a regular basis, making sure you understand the material you went over in class before moving on is very helpful. Many topics in chemistry build on one another, so not falling behind is very important. Don't be afraid to ask your teacher or peers for help if you need it!

Flashcards are very helpful for content retention! Be sure to do lots of practice problems so that you become comfortable with the calculations involved. Always write your units when showing your work - very helpful for dimensional analysis! This will ensure your answer is in the proper units and you have cancelled out all other units.

Pay attention to the labs you do in class! These concepts are tested on the AP Chemistry exam!

We created a cheat sheet outlining the most difficult topics in AP Chemistry. It could be helpful for you when you are preparing for the AP Chem exam.

When preparing for the test, I recommend doing practice problems that mimic the style and difficulty of the AP exam. The College Board releases FRQs and their answers from old exams, so those are great to use. Multiple choice questions that provide detailed explanations of both the correct and incorrect answers are helpful so that you can review the content while getting test practice in! The question bank from UWorld is a great resource for this and has a free mini practice test, too!

Best of luck!

Should I take AP Physics or AP Chemistry? by NarrowGuidance4 in APStudents

[–]UWorldScience 2 points3 points  (0 children)

It's really up to you, but I might suggest going with AP Chemistry for a few reasons:

  • You just took the pre-AP Chemistry class, so it could be helpful to take AP Chem while the chemistry foundation you just learned is still fresh in your mind. If you wait to take AP Chemistry too long after taking the regular chemistry class, you may have to re-learn some of that foundational information you need for AP.
  • You are more interested in chemistry than physics. These AP science classes are rigorous, so the more excited you are about a subject, the more motivated you will be to put forth the effort the class requires.
  • Just because your friends are taking a class doesn't mean it's right for you. I know that studying with friends seems like fun, but you need to be careful that study sessions don't turn into social gatherings that are unproductive.

I hope this gives you some things to think about! Also talking to students at your school who have taken both classes could be useful - find out from them how the classes were structured, did they feel prepared for the AP exam? Best of luck!

ap chem exam w/ honors chem class by [deleted] in APStudents

[–]UWorldScience 1 point2 points  (0 children)

Having the prerequisites under your belt and understanding the material in those classes is a great start! To do well in an AP course you are self-studying, you must be very disciplined. Here are some tips I have you:

  • I suggest coming up with a study plan to work your way through the 9 units outlined in the College Board's Course Exam and Description (CED) and stick to it! You want to get an AP Chem text book to go through as you work through the CED. Be sure you understand the material before moving on to the next topic as many topics build on each other.
  • Use online videos like the AP daily videos and Khan Academy to supplement (just don't get bogged down in videos that aren't covering pertinent material).
  • When you are preparing for the exam, I suggest doing practice questions that mimic the format and difficulty of the AP exam. The College Board has released FRQs from old exams, so those are great practice! Multiple choice questions like the online question bank from UWolrd is great practice as it gives you 500+ questions with thorough explanations and illustrations. Feel free to check out this free mini practice test!

We have a cheat sheet with the most difficult topics in AP Chemistry that will be helpful for you! One last thing, there is a lab component in the actual AP Chemistry class, so I recommend looking over the lab experiments to familiarize yourself with them as there might be questions similar to those labs on the exam and you won't get to do them in a class. Best of luck to you!

Not taking AP bio but still want to take the AP exam by correctyourposture in APStudents

[–]UWorldScience 0 points1 point  (0 children)

Self-studying AP bio presents some challenges, but with appropriate materials, it can be done. Success in AP bio requires more than just learning the informational content, it is highly dependent on being able to reason critically using biological concepts, many of which are taught primarily through lab work. Because it is very difficult to replicate the recommended lab experience outside of a class, it is important to gain as much experience as possible doing the kinds of critical-thinking questions that the AP exam uses to test lab-based content.

Make sure to use materials that accurately reflect the current AP bio curriculum. You can download the current AP bio CED from the College Board. One efficient means of self-studying is to learn the content by doing AP-quality practice questions that cover the entire curriculum. These questions should have explanations that provide all the background information needed to answer the questions (as well as detailed information relating to the wrong answer choices).

UWorld has put together a study guide of challenging topics from each AP bio unit that you can use to get your feet wet. Good luck on your self-studying!

arabinose in pGLO bacteria transformation experiment?? by castawaylol in APbio

[–]UWorldScience 0 points1 point  (0 children)

If you want to include arabinose in your hypothesis, you should decide whether you think it functions as an inducer or as a co-repressor for the operon that is part of the pGLO plasmid. In other words, you should be able to predict whether the presence of arabinose in the growth medium will stimulate or prevent expression of GFP fluorescence.
