I wanna to apply to medical, dental, and optometry schools. I now use the Kaplan and EK book sets to study for the MCAT. Since you guys know all about the OAT, DAT, and PCAT, can my MCAT prep be used to prepare for those tests? Or do I have to study for them separately using their own study materials?
MCAT is passage-based, the others are not, so right away question types will be completely different.
OAT and DAT have the same test maker, so the quantitative reasoning, reading comprehension, and Bio/Chem/Ochem sections are exactly the same, but all different from MCAT. The big difference between the two is DAT has perceptive ability, and no physics, while OAT has physics and no perceptive ability.
Perceptive ability is its own animal completely, so you would need to get some separate practice tests on that at the very least least.
OAT and DAT both have an entire quantitative reasoning section which is very similar to SAT math, and not present in MCAT at all. Honestly, doesn't really require studying, though.
OAT/DAT reading comprehension section is much more detail-oriented than MCAT. Questions are more in the "what did the author say" range, rather than "what
would the author say" like you find in MCAT.
OAT/DAT sciences are more detail oriented than MCAT. Read: more memorizing. You have to know plant bio and taxonomy, neither of which show up on the MCAT, so they won't be in your MCAT study guide.
PCAT requires calculus. 'Nuff said.
TLDR: You need separate materials for all of them, and you're splitting your focus so you'll do worse on all of them than if you just studied one and owned it.
