[@georges.7386]

True story: I watched this and (pretty much) only this like 8 hours before I took the exam. I solved each of the problems with him and labeled each of the numbers for what topic they covered (example; number 20: buffers). I looked over them a few times, and more or less learned what to do with them (although I wasn't too diligent on them). I got an 80 on the exam, which was perfect for what I was going for, a B in the class, but if I had taken a bit more time just on these questions, I think I could've gotten an A on the exam, with some luck.

FINAL EXAM TOMORROW MORNING

[@robertcook7429]

I would like to thank you for making this, I had an exam today, and I was feeling pretty nervous before it, I watched through this and did the problems, and it gave a a great confidence boost, during the exam everything clicked, and that never would have happened if I was panicking.

[@FlamingWinges7]

I thought I was doing good 2 hours in.. then he said "I linked the full 7 hour video in the description, this one is a trailer" and my heart sank and the "ohh no, ohh no, ohh no no no" song from tic tok started playing in the background💀

[@haileycat2105]

I thought I was doing so well too

[@Hidlayk]

I should have been using this from the start. Once you get halfway through the video he shares the link for the longer video (7hours). I wish I would have used this rather than the ACS workbook. This also would have been great to use as a practice tool throughout the semester. Thank you "The Organic Chemistry Tutor" for making such a thorough video. I will be using your organic chem videos next.

[@XTheSpartanX7]

wait, when do you see the link for the 7hour one ?

[@fyreritala]

vimeo.com/ondemand/genchem2finalreview For anyone wondering, that's the link to the 7hr version. It does cost $50+ to watch, but it might be worth it if anyone feels really doomed for Chem...

[@iamaninjaturtle30]

YO GUYs I just took this exam and literally if you get this video you’re going to be just fine. I didn’t believe it at first but like as you go on you’ll realize the questions are SO SIMILAR like deja voo

[@spidrawebster]

I wish I'd discovered your fine work earlier. Since your user name said "Organic", I assumed it was only for students in organic chemistry. Thank you so much for breaking the algebra steps down as much as you do. That is my bête noire in chem class. I really appreciate your work. Thank you so much!

Hey I took my final exam today for 2nd semester gen chem and your video definitely helped me score some answers! While taking my final I wished I would have finished the entire video! Lol

[@jackbauer408]

Thank you so much for this!!! It’s so helpful and really dumbed down the acs practice questions for me! I’m gonna destroy this exam now!! But I have a suggestion for this video that I think can really help! Can you put the times in your description for each subject so students who are struggling in a certain part of the course can instantly jump to the examples and not have to scroll through? It’s something minor but I think it can really help!!!! :D

[@jaesim3150]

I just took my ACS gen chem 2 exam and got a 96 thanks to you. You’re tHe savior

[@InsecureRaven826]

I don't think words are capable of describing how much of a hero this guy is.

[@Jackson-gu3dy]

Probably spent ~5 hours watching this video and taking notes prior to my final, and some things transferred over well. Unfortunately, a lot of what I remember learning throughout the semester from my professors, midterms, and even this video, were worded very differently on the ACS final. That being said, my score put me in the 90th percentile, which I was pretty happy with. Whether or not you see a lot of questions formatted similarly to the ones in this video, the way the Organic Chem Tutor explains various concepts is very helpful!

[@mariahmartinez2082]

Thank you so much! scored in the 80th percentile from this video! I took summer chem 2 so all of the info in such a short amount of time was hard to remember but this video helped a lot

[@tedjohnson5579]

This is a great video and I appreciate this a lot going into my ACS exam. But I would like to add that on question #26 you have to use either the [base]/[conjugate acid] or [conjugate base]/[acid] not the [base]/[acid]. The right answer to the question if a pH of 3.17 not 8.61. You would want to find the conjugate base [F-] because there will be less work to be done since we are given the ka value for HA being 6.8*10^-4. DO this by understanding that the ions will dissociate to HF+F- HF2- Since the Acid is HF then the F- is its conjugate base. (there are too many Fs just kind of try to keep track) anyways Kw = Ka x Kb 1.0x10^-14 = 6.8x10^-4 x [F-] [F-] = 1.47x10^-11 M plug this found conjugate base in with the original acid pH = pKa + log([conjugate base]/[acid]) pH = -log(6.8*10^-4) + log(1.47*10^-11/0.755) pH = 3.17

[@denissemitchell9891]

If anyone is taking the ACS 2nd semester gen chem final you need the know that most of he exam was on kinetics and buffers and mixtures!

[@denissemitchell9891]

Acids and bases*

[@marcoghilotti9087]

Hey! I wanted to ask you a question. Was there any " Intermolecular Forces and the Liquid State/ Chemical Mixtures: Solutions and Other Mixtures " on the exam? Since he doesnt talk about it on the videos.

[@johndove2939]

n = log(rate2/rate1) / log(M2/M1) The power of the concentration equals the log of rate 2 over rate 1, divided by the log of the 2nd concentration over the 1st concentration.

[@joegabrail7175]

Just took the acs exam this week and this video does a decent job at preparing you for the acs exam. The ACS exam had like 5 questions about heat of fusion questions and 2 questions about solids, got a 67%(before the curve) after watching this video and studying all the chapters. This is coming from a student who had a 96,96,100 on the three exams for the exams and refused to buy the acs book. So to anyone in the future that needs to do well on the acs exam, buy the book. I choose not to because I had wiggle room to mess up and still ace the class.
