Hi noorjihan2004 - we're glad to hear that you're finding the course useful! As for unit updates, we're working hard at creating new content and expect to have Unit 4 complete by the end of this year and another unit complete by the 2021 exam (for a total of five units). In the meantime, make sure to check out our older AP Chemistry course for more videos and articles covering topics in the later units. I hope that helps, and happy learning!

AP Chemist beta is coming up amazing! It has been great to learn form it

Thanks, Vinicius Tognetti! We're happy to hear you're finding AP Chemistry beta useful!

As of November 2020, Unit 3, Intermolecular forces and properties, is complete. Unit 4, Chemical reactions, is partially done. One warning regarding Unit 3 - it has 14 skills and thus 14 questions on the Unit test. For those intent on getting 100% mastery, this could mean taking the test multiple times before finally achieving mastery. For me, it was 4 times. These units of more than 9 skills (since 9 seems to be the minimum number of questions on a Unit test, even if the unit has fewer skills) need to be split up to avoid such long tests at the end. Or come up with an alternate way of achieving mastery without putting as many as 13 skills already mastered at risk for losing mastery. The old missions system was great. It would have been nice to have had a World of Science to go with the World of Math.

Thank you for your feedback, Regina Litman - we'll keep it in mind for when we make improvements to Unit 3 in the future.

When will the AP Chem beta course be completely finished?

Hi Arav Popli! The first version of the course is expected to be completed by August 2021. From there, we hope to make improvements and expand sections on a rolling basis. I hope that helps!

Good news for website and Android app users! Unit 4, Chemical reactions, appears to be complete on these two platforms. A unit test and unit quizzes have been added, the practice exercises have been converted to ones that can achieve up to 80% mastery, and mastery percentage now shows. If you haven't started it yet, it will show as 0/700 (0%). New videos have been added, including ones for the two practice exercises that didn't have any educational material before.

Not-as-good news for iPad (and possibly iPhone) users. The unit test and unit quizzes are there, the practice exercises have been converted, and the mastery percentage shows. However some of the new videos are missing including the ones for one of the practice exercises that didn't have any educational material before.

I have submitted a Report a Problem concerning these missing videos. Lauren Rosebrugh, can you also look into these missing videos if you are able to, please? Thanks in advance. Emoticon-free/emoji-free responses appreciated.

Hi Regina Litman - submitting a Report a Problem is the best way to get the ball rolling on this issue. Thank you for doing that! You should be hearing from our team soon (if you haven't already).

Good news for iPad app users! Unit 4 appears to be complete there now, too, with the videos that were added yesterday now appearing. I don't know if reporting the problem did the trick or if it was just a slower roll out process. I look forward to completing this unit. As you may know from my earlier posts, I am an adult learner who never got much exposure to chemistry in high school and never bothered to take it in college. I'm not planning to take the AP course, but I wanted a rigorous course of study. Once I finish what's available in AP/College Chemistry beta, I will continue watching what's available in the current AP/College Chemistry and Chemistry Library. When more units are filled in for the beta, I may try them, although I may have moved on to Biology and/or other Khan courses by then.

Lauren Rosebrugh Thank you for patiently answering all of our questions about AP/College Chemistry beta. As you may know, I am an adult learner, but I went through what you already have for this course in order get a rigorous introduction to the subject. I look forward to the rest of the units being added. In the meantime, I have continued with the existing AP/College Chemistry videos and articles and then will view any that are in Chemistry Library that aren't (yet) in either of the AP/College courses.

When you do add units to AP/College Chemistry beta, please be sure to announce them here in Community -> News and Updates from Khan Academy so that all of us who are looking forward to them will know about them. I plan to move on to High School Biology and then AP/College Biology after Chemistry, but I may put whatever I'm working on then aside and go back and fill in the Chemistry gaps. You could put them as new messages in this topic, but it's gotten pretty long. So you probably should start a new topic for such announcements.

Please do not just put them in the https://support.khanacademy.org/hc/en-us/sections/115000894871-News-and-Updates - I don't check there regularly enough, and I often miss things that are posted there.

When are you going to put a High School Chemistry course?

Hello,

Is there an estimated date for when all of the units of AP Chemistry will be covered for this beta course. Can all of the units be added before the 2021 AP Chemistry exam?

Hi SrinivasGUSA - we are currently working on developing new high school science courses, including a high school chemistry course. Stay tuned!

Hi Yaniris Rodriguez! We're working hard at creating new content and expect to have three more units complete by this year's exam and the remaining units complete by August 2021. In the meantime, make sure to check out our older AP Chemistry course for more videos and articles covering topics in the later units. I hope that helps, and happy learning!

I love this course and I have been using it to study for my AP chem class this year. Thank you guys for putting it together!! My only recommendation is having practice FRQ's. Like for every sub unit I know there are multiple choice problems, but it would be nice to have frq problems where you write your answer and then when you submit it you could compare your answer to a correct sample response.

Im grateful to you.I prepare for ap exams and you help me extremely a lot.I do not have the chance to take ap prep courses.Good to you are doing this.I hope you will add the left units of the ap chemistry beta course.Thank you sooo much.

Phoebe We're happy to hear you're finding the course useful! Thank you for your suggestion about adding practice FRQs - we'll keep this in mind for expanding the course in the future.

asanazra9 We're glad the course has been so helpful to you! More units are on the way soon!

This is so helpful! How many units do you expect will be part of this course by the 2021 AP Chemistry exam?

anniobr9576 Good question - we're hoping to release content for one or two more units before the 2021 exam. I hope you'll find them helpful!

Lauren Rosebrugh (and everyone else), I just discovered that a new unit, Kinetics, is now part of AP/College Chemistry Beta. This includes 6 playlists, but the last one, Catalysis, only has videos, no practice exercises. There are two Unit Quizzes, both of which come before the Catalysis playlist, plus a Unit Test, which does come after Catalysis.

Will there eventually be a practice exercise for Catalysis? And if one does get added, will this mean that the Unit Test will have this additional skill added to it, thus making someone who had already mastered this unit have to go through the Unit Test again to get 100% mastery?

I first saw this new content in the iPad app. Since I know that sometimes content is incomplete in the apps, I checked the website to see if Catalysis has a practice exercise there. It doesn't have it there, either.

Now that I see this new unit in AP/College Chemistry Beta, I plan to start working on it early next week, on either Monday or Tuesday (February 8 or 9/8 or 9 February). It will probably take me a while to reach Catalysis, so if there is currently a missing practice exercise, it will be there by the time I'm ready for this playlist.

Regina Litman There are currently no plans to add a practice exercise for the Catalysis lesson. I hope you enjoy working through the new unit!

Will this Chemistry course be updated for the 2021 AP Exam? 

Hi Kusuma Teluguntla! Yes, we are planning on adding videos and exercises for Unit 6 and exercises for Unit 7 in time for the exam in May. We also recently updated the course with content for Unit 5, which you can find here. Best of luck with your exam preparations!

Lauren Rosebrugh Awesome! Thank you so much! And this is a fast response from Khan Academy! 

Will the AP Chemistry course be completed before the may exams for 2021?

Hi sverma23 - we'll be adding videos and exercises for Unit 6 and exercises for Unit 7 in time for the exam. I hope you'll find them helpful!

I am working on an independent study AP Chem course for one student who requested it at my school and I'm wondering if there's any chance that by January 2022 there are plans to have unit 6 and 7 done. I love the structure of the first 5 units and will definitely use them often!

Hi rthies! Current plans are to release content for all of the remaining units (6-9) by the end of this July, and then add some additional exercises to the course by the end of the year. I'm glad you're finding the first five units so useful, and I hope the same will be true for the rest of the course!

This course is great! It is way more engaging than the old AP Chemistry course and feel like I learn a lot more. I have just one question, will there be an organic chemistry course like this one with questions and mastery?
