I haven't even watched all of your excellent AP review videos yet, but my (initially shaky/uncertain) confidence level has already recovered by numerous magnitudes--in other words, I feel a lot more comfortable with passing this exam! While the official AP review (and AP Daily) videos were somewhat helpful for me earlier this week (well, last week, I guess), your videos *OVERWHELMINGLY* surpass theirs in terms of content, helpfulness, and a well-made, straight-to-the-point style _(the subject IS the introduction here, which is greatly appreciated)._ My confidence has already experienced an upward trend (again, earlier this week), but your teaching style has accelerated this trend in a truly exceptional, unparalled way. Overall, I'm overjoyed to have found your channel earlier today (4/30/2023) just by searching "AP chemistry 2023," and now I feel more like a 4/5 than even a passing 3! God bless you, Mr. Krug! I really appreciate these videos!
Thank you so much for your kind words, @Supersonic246 It sounds like you're on track to meet and even surpass your own expectations. You're going to do great tomorrow!
@@0xCUBE Oh, thanks for asking! Despite my MCQ _and_ FRQs being pretty spotty in terms of personal confidence (both similarly), I ended up getting a 3! While subjects like Unit 9's galvanic/electrolytic cells were very quickly skimmed over in my high school's AP Chemistry class (days before the exam), I answered everything I could to the best of my ability, using a mix of Mr. Krug's lessons & my in-class memories to guide me along. Overall, that exam was exceptionally difficult, with me hoping & praying to see a 3 instead of a 2 about two months after taking that exam. Even still, like I said in my comment above, my comprehensive chemistry review (cram) sessions truly helped make the score more achieveable! - Timothy D, 12/27/23, 8:44am.
fellas, good luck today last minute review before the test goes hard! hopefully this isn’t your first time reviewing for this class because that won’t be good!
You're very welcome. I wanted to make some short, but to-the-point videos, and I was hoping 10 minutes would be just long enough to get all the major points in there.
Thank you man, we have a test on this tomorrow. This is really helpful. I will be sure to come back to watch more for my final and the AP Test later in the year ofc
Tbh, I took AP Chemistry in 2017. Got a 4 on the exam, then I minored in chemistry at Purdue but haven’t reviewed chemistry in 2 years now. So I’ve watched you’re videos just to refresh my mind because I want to ensure I still remember Intro college chemistry. So far so good
9:18 - Wavelength is typically given in nanometers so there will be some dimensional analysis/factor labeling, but other than that great video! Really helped refresh the concepts for the test :)
Good point! To keep from making a mistake with the dimensional analysis, I tell my students to keep it simple and just write 750 nm (as an example) as 750 x 10-9 m.
@@JeremyKrug I have a long question regarding intermolecular forces and their formation in typical reaction vessels when T is held constant and P is either increasing or decreasing. Given the pressure vs. temperature curve we often see when studying the phase diagrams (gas, solid, liquid, supercritical fluid) of a substance, we typically see that when increasing pressure at a constant temperature either 1. deposition can happen, or 2. condensation and then freezing. If a substance condenses before all the other substances at the LOWEST pressure, does it have the STRONGEST intermolecular forces under increasing pressure. And would the forces be the WEAKEST when the substance condenses at the highest pressure of the substances when increasing?
reminder that the gas constant, R, changes depending on the measurement of pressure used. It is .0821 for atm, see the other measurements on your formula sheet, I forget them myself
thank you so much for this review! i self-studied AP chem and this is making me feel a lot more confident. one question though, how do i identify a covalent network? i did a question (2019 FRQ, i think) where it asked to explain the difference in melting point of SiO2 and SiO4. the answer was because of covalent networks. are there some common network formulas i should memorise or is there a rule? thanks!
These videos are great but its been a while since unit 3. Can u make another video deepening / explaining each topic? like for unit 3.2 what is a molecular solid or covalent network how to find those things, and maybe an example question?
Have you seen my full course playlist that explains every one of the 91 topics in detail? Here's a direct link to Unit 3 videos: th-cam.com/video/a9YtU828MzM/w-d-xo.htmlsi=hMzN-OR8iCQLVtt3 Thanks for watching!

literally my lifeline before every ap chem exam, ur great man!! seriously helps me review over everything and refresh on what we covered
Glad to be of help. I hope these quick 10-minute reviews help get the main points in mind before your exams!
Thank you a lot for your review videos!!! They are so concise and accurate. Really ideal for a quick revision!!!!!
Thanks for watching and for your kind comments. I'm glad you're able to use them as you review!
thank you so much for this video!!! ☺I recently took the unit 3 quiz and got a 8/10 while the class average was a 4/10 😃
Im proud of you, Daphne. Great job!
krug you have saved my confidence thank you so much🙏🏼
You're welcome, Owen. You've got this!
Go owen 🎉💪
6:28 I don't get it. Why is it loosing 6 electrons?
Thanks for the videos, I just want to pass this test!!
I want you to pass this test, too. You've got this, Nichole!
youre actually amazing these videos are helping me for the final review before the test. Wish us luck!!
Good luck, Mera! You've got this!
Just finished Unit 2 might as well watch this video too. Love your videos, Mr. Krug! 😊❤
Thanks for watching! I hope you're able to get some good review here.

Absolutely right! When we use R for thermodynamics, it's 8.314 J/mol*K.

The most common covalent network solids they ask about are SiC2, SiO2, diamond, and graphite. I hope that helps!
@@JeremyKrug thank you so much!
For a frq can we explain that a molecule dissolves in water because "like dissolve like"? Or we need a more formal way of describing it?
"Like dissolves like" is a nice mnemonic aid, but you'll generally need a more detailed description of the forces involved to get credit.
Insanely helpful!
Thanks so much!
Here we are, like 3 hours before the exam
It's going to be a GREAT day!

at this point my goal is a 2 or 3, which is bad, but before finding these videos it was a 1, so thanks dude :)
All improvement is good. Keep working, and I know you can get that 3!
