"Not taking my own notes seemed like a death sentence to my grade, but after reading the first 3 sections of General Chemistry Notes, that's exactly what I did. Not only did I stop taking my own notes, but I sold my G-Chem textbook to another student. It sounds crazy but I no longer needed it because I was able to keep my A grade simply by using your Notes alone."  -- Amber C.


"Before finding the chemistrynotes.com website, I was completely lost in my Organic Chemistry course. I'm a good student, but this class and the corresponding textbook were simply overwhelming. After buying the Notes, I've seen my grades increase dramatically. All of my friends are using notes from Organic Chemistry Notes too. Very happy I found this site!"  -- Kim H.


"General Chemistry Notes helped me make sense of the difficult topics that I was unable to understand in lecture. Using the Notes, my study time was well spent because I knew I was focusing on what really mattered to my grade."

Before: Studied 10 hours/week -- overall grade = C
After: Studied about 3.5 hours/week -- overall grade B+    -- Huang F.


"Who would want yet another source of o-chem material? That's what I was thinking at first: I have ENOUGH o-chem crap to study! A textbook, tons of my OWN notes, worksheets, problem sets, old quizzes/exams, etc. Well, after buying the full course version of Organic Chemistry Notes, that's all I needed. Everything else became obsolete. Thanks guys!"  -- Sara K.


"I figured General Chemistry Notes would help me 'fill-in-the-blanks' with my own general chemistry lecture notes. It was a nice surprise to see that your Notes were so useful and helpful that I actually stopped taking my own lecture notes altogether. I just recently gave your 1st Semester Notes to my friend and he's stoked on it!"  -- Clayton R.


"Unbelievably helpful. The fact that they are handwritten is very helpful in showing the arrow-pushing by the way. I no longer use my textbook. Saves me so much reading! I'd sell the book if my prof. didn't assign problem sets from the back of each chapter."  -- Jason S.


"My General Chemistry [text]book was so difficult to understand that I decided to give General Chemistry Notes a try. I was worried about purchasing it mid-semester, but it was so easy to use! I started on Section 4 in the Notes and after a week I realized that I no longer needed by Chem [text]book. My study time has gone down but my grades on tests and quizzes are going up! Thanks for the help!"  -- Ling H.


"I'm a pre-med student at [university's name removed] and with more than 400+ students in my O-Chem lecture, the curve is very competitive. When I was a freshman in General Chem, I always heard that O-Chem was the "weeder course" for students who wanted to go to Med. School. Now I know why. I kept getting B after B and I was sick of it. So, I googled "Organic Chemistry Notes pdf" and found your Notes. You have no idea how much you've helped me. I ended up getting an A and now I'm wondering when/if you'll ever have Biochemistry Notes?? LOL. Thanks again."  -- Han N.


"I'm hesitant to buy products online, but the process with you guys was so safe and hassle-free that I'm glad I did. In retrospect, it's a no-brainer to buy these Notes. I just wish I'd bought the whole thing all at once -- I bought Section by Section as I needed them. :-( But, oh well. They were only 7 bucks each..."  -- Christopher B.


"A friend mentioned Organic Chemistry Notes because he knew I had a D+ in the second-semester of my Organic Chem course. He's not taking ochem but he used your "General Chemistry Notes". I finished the semester with an A-. Granted the D+ was my grade very early in the semester, so I had a lot of time to catch up, but I wouldn't have gotten an A- without using your O-chem Notes. I think my grades improved because I didn't have to take notes in lecture anymore. All I had to do was LISTEN -- so much easier to retain the important info from class!!"  -- Rebecca P.


"I'm a busy guy and didn't have much time to spend on my chemistry class. General Chemistry Notes is the ONLY reason why I passed both Chem 1A and Chem 1B."  -- Marcus L.


"I'm a visual person and a visual learner, so I thought all of the organic molecules and organic structures would make it easier for me to learn Organic Chemistry as compared to General Chem. Um, WRONG... Sooooooo many reactions to learn. Your guys' O Chem Notes made it much easier for me. Without the Notes, there's no way I would have enrolled in the second-semester of O Chem. So, thanks."  -- Dieter G.


"My Gen. Chem. professor was awesome, but I was missing half of the lectures because I was always face-down scribbling notes. And the textbook was sooooo confusing. So, after checking out all of the free pages of your Notes, I knew you had a good thing here. That's why I bought the full General Chemistry Notes course (downloadable format by the way - easier cuz instantaneous!). I told myself that a better grade and a better understanding was worth the 45 bucks. Plus I hated taking notes during lecture. I mean, who wants to draw p-orbitals?!"  -- Juliana S.


"I'm a college athlete and don't have much time to devote to my Organic Chemistry class. Organic Chemistry Notes is the ONLY reason I passed Chem 140A and Chem 140B."  -- Mark T.


"At first I was thinking to myself that I have ENOUGH chemistry material as it is. My own notes plus a giant textbook. Why the heck would I want to buy more chemistry stuff to study from?? Well... that's what I USED to think, lol. I bought Sections 8 and 9 because I could not understand Lewis structures and VSEPR theory. After reading/studying those two sections, I went ahead and downloaded the entire two semesters of General Chemistry Notes because I knew I was going to need them for the rest of the first semester, and all of the second semester. Your Notes have made all the difference! It's obvious that you know how to get the message across in a simple-to-understand method. And about buying 'more materials'? --> I abandoned my textbook and stopped taking my own notes, so now I'm studying straight from your Notes (less material) by matching up your SECTIONS to my book's CHAPTERS (which is easy to do btw!)"  -- Taylor H.


"Seemed kind of scary at first: not taking notes in class when all the other o-chem students are busy scribbling away, but after reading sections 5 and 6 (my initial purchases) of Organic Chemistry Notes, that's exactly what I did. Heck, I even stopped reading my Organic Chemistry [text]book too. Sold it for way more $$ than I spent on Organic Chemistry Notes by the way. Haha. Funny thing is this: I just used your Notes instead of reading hours and hours of difficult textbook material, and when you include the fact I was no longer taking lecture notes, I was able to boost my grade to an 'A' WHILE doing less work."  -- Aarif S.


"Let me be an example of why you will benefit from Organic Chemistry Notes:

Before buying the Notes = was putting in (literally) about 12 hours/week of studying -- C+ grade

After buying the Notes = put in roughly 4 hours/week of studying -- A- grade (no lie!!)"  -- Aiko F.


"Some advice: buy either the entire first semester, the entire second semester, or the full course. It'll save you a ton of money. Cuz if you buy one section for $6.99, you're gonna want to buy every single section. These Notes are UNREAL..."  -- Shawn L.
