Kaplan VS Dr.collins (Chem section)

[Peoni]

Advertisement - Members don't see this ad

I am using both Kaplan and Dr.collins for preparing the chem section

and I noticed that there are lots of concepts in Kaplan whereas it's not covered in Dr.collins. ( i.e In gas law section, Kaplan covers 'Graham's law of diffusion and effusion while Dr.collins doesn't mention it)

I've heard that Dr.collins are more reliable but don't feel comfortable leaving the stuff (like graham's law) thinking that it might be on the PCAT..

Please give me some advice 😕

Honestly, will it take more than 2 minutes to review the key concept regarding Graham's Law of Diffusion? No.

Frankly ... when in doubt, know everything. However, if you spend ANY time worrying about a concept like that, you are completely wasting your time and will ultimately score poorly because of it. Biology is the section where you'll see more randomness with respect to questions, not Chemistry.

I would know grahams law because I was asked that question and didn't know it cause I depended heavily on collins for chem.

Kaplan's chem section is sure to give the most laid back of folks apoplexy! Collins section by a long shot!

@harmonidrum - i hope you're right about that. after practicing with mostly collins exams, i started taking the few kaplan ones and the kaplan chem scared me because i had no time to finish it! collins seems more based on concepts while kaplan is all about equations and calculations. i hope by your comment above, you have seen that the actual pcat is also based more on concepts (like collins) than kaplan.

I scored 98th percentile on the chemistry section, without using Kaplan.

Did you use anything else besides Collin's, especially for ochem? I've gone through the Collin's chem packet once and lately I've been reading from my ochem book and using this website from a MCAT prep class offered at UT but I don't know exactly what to study. Mainly I've been focusing on hybridization, Sn1 reactions, Sn2 reaction, nomenclature, functional groups, Markovnikov addition, anti-Markovnikov addition, how to break double bonds with H2 and different catalysts. I'm not really sure what else to cover.

I read through "organic chemistry as a 2nd language" as well. It was very helpful

Thanks brother, you've been a big help so far and I really appreciate it. I'm reading it now.
