I did horribly in ochem during undergrad so I knew that I really wanted to show the admissions committee I could improve at the subject on my DAT! I made flashcards FOR EVERYTHING. Every. Single. Reaction. But beyond memorizing reagents and products, I tried to really UNDERSTAND the concepts of WHY things were happening. For me this was really helpful, because if I did forget a reaction I could rely on my chemical thinking to get me through a problem. I have always thought that chemistry is definitely something that should be understood rather than memorized.
Get good at what you are good at and understand what areas you struggle in. When you find a difficult area: pause and go use other resources to dig deeper (youtube, old chem books, Chad's videos).
I skipped HNMR, CNMR, and any kind of spectra...for me this was a waste of time and brain space. I only got asked one question on this topic.
If you know generally how electrons move and why they do what they do you can figure out a lot of ochem without memorizing!
I felt ochem destroyer was WAY harder than the ochem on the DAT. I felt like the chem section in destroyer was = to the DAT.
Group all of your similar reactions together using charts!!!!! Give a special look at reactions that appear similar but are completely different****
Overall, you just really need to break this subject down to its bare bones and organize reactions in a way that makes most sense to you. Make packets, charts, and flashcards.
Coming from a previous ochem failure - THIS SECTION IS POSSIBLE TO DESTROY!!!! You just definitely need to grind.
My Ochem Stats:
B- Ochem 1 (no idea how I pulled this off)
C- Ochem 2 (don't know how it wasn't a D...got a 49% on my final)
DAT = 21 in the ochem section!!!
You can seriously do it you just really need to commit!
AND in regard to Chem:
Memorize the basic formulas: Q=mcat, Pv=nrt... blah blah blah and write these down IMMEDIATELY on your notes page during the exam. I would look at the question and see what information I was given then I would try to fit that into a formula. Generally it would work! Practice your math skills and know molecular and empirical formulas. Practice practice practice.
