Does anyone know of a tutorial or even book that teaches electrostatics well??? I am really having trouble with that topic. I dk if it is commonly tested on the MCAT but if it is does anyone know what they usually ask??? Thanks for any advice.

If you have TBR, then I would use that, but since the both of us are taking the test next week I would just focus on the basics:

Coulomb's (particularly the 1/r^2 relationship).

Know F=qE and be able to turn it into mg=qE, and Work = qED.

Know Amps = C/s (I had to use this for a problem in the AAMC book).

Know the right hand rule, and be able to apply it quickly.

Know that you can multiply Coulombs law by distance to get work (because F x d = work).

Know that you can multiply the Electric Field by distance to Voltage (V = Ed)
(which can be done via Coulomb's again)...this also showed up in an AAMC book problem.

Know units! Be able to convert Joules to eV and visa-versa.


If you go on youtube you can find some great tutorials from India, but most of them are calculus intensive and not worth it for the MCAT.

I am sure I am might have screwed something up or missed something, but anyway, WE ARE ABOUT TO TAKE THE TEST!!!!!!!!!

good luck man!

I know, I know haha it is really soon but I thought I might as well ask and get some tips. Thanks from both of you. Actually helped out. I still hope a passage on it does not show up on test day haha

I encourage you to check out Derek's website here:

I emailed him and he was selling all the physics course video to me for $29. The only downfall is that the videos don't cover fluids. But they cover majority of the concept and they are amazing. I loved them.

Sorry, though these videos are for highschool students, they are incredibly good for the MCAT since they emphasize understanding over plug-and-chug.

wow...thanks man. That really helps I will watch some of those...wish i got my hands on these a month ago. Great website.

Go to MCAT-PREP.COM and click on videos. There are videos that help with the different topics within the subject.

Use your textbook. That's the most comprehensive and reliable source ever.
