@romeofuntila2288
Your math, chemistry, and physics videos are what got me through the four years of my Biology degree. You are a hero. You deserve the Nobel prize.

Imagine, this 2-hour lecture covers a whole semester. Big salute to this channel.
@dommy1495
Whoever else is watching this right before their exam...GOOD LUCK!!! YOU CAN DO IT!

37:41 summarizes my year in chem so well. "So uh we gotta use that criss-cross thing."
@dirchhd6985
Things you should know about not mentioned in the video: Know that transition metals require a number for instance CuSO4 would be copper 2 sulfate. Make sure you know what a pure compound is and a pure substance. Also make sure to know what dipoles are and if you have say 10g of C2H4 make sure you can figure out how many moles or grams you have of say carbon or hydrogen. Don't forget about sig figs and how to name acids. ate - ick, ite - ous. Make sure to remember how to identify aqueous solutions and solid solutions. There's videos to remember such as NAG SAG. There's also acronyms to remember strong acids and know that all strong bases have OH in their formula.
@TheReck12
When it comes to ACS exams I've noticed the actual chemistry isn't difficult rather learning to understand what the questions are asking is more difficult
@yakyakjack
Watching this after failing the final is like watching the evidence unfold in court.
@cheyeb.7779
am i watching this the night before my final? yes. will i be passing the exam? a hard maybe.
@sanjanaanur4267
You are the type of people that need more viewers and subscribers, not other silly videos here on Youtube. Thanks for helping those who are struggling, you have a kind heart.
@dawsonboes3341
Thank you so much! This should seriously help with my final tomorrow!!! I don't know if you are employed as a teacher, but you should be. You explain things really well--that is a quality that most teachers don't really have. They all just spit out info and tell their students to study. They work out practice problems without explaining them, it is pretty rough out there. Keep up the good work dude!
@Layla-qk6kt
dear organic chemistry tutor, thank you so much. after watching your videos, I scored a 5 on my AP chemistry exam and finished the class with a 100! your videos are carried out very smoothly and have given me a great understanding on many topics. thanks for renewing my passion for chemistry!!! i hope to donate to you in the future :)

@anangelsdiaries
For those wondering at 8, why he simply added 1 and 2 to them. It's because the concentration we are looking for is actually the concentration of H+ ions in the solution, but since there are two moles of H in the molecule we have to add that 2, on the other side since it's a base we have the OH- concentration, however since there is only on mole of OH, the coefficient in front of the m1v1 is well 1. Hope it makes sense, and that I am not mistaken hahaha.
