I feel like since we're presented with so freaking much information, it can be so overwhelming to try and learn it all. I don't know for sure, but if this is you and the learn it all plan is backfiring, try this: Not quite limit your studying, but instead focus your studying to the big picture/idea/concept and just letting the other stuff go. You'll never learn all of the tiny details anyway and you're just filling your brain with vet med trivia facts that way. Besides, no matter how may trivial details you remember, guaranteed that the professor will ask about the other even more minute fact that you can't quite remember on the test anyways. Instead of memorizing every ad nauseam list presented, just remember the two most important things on the list. If drug categories, mech of actions, species, aliments indicated for, contraindications etc etc etc, are too much to remember, make a limited information comparison chart for that class of drugs. Add only the most important information. Do the same thing in other subjects, but with flow charts. I find this type of studying is very effective and gratifying for me. Granted I do miss some of the really trivial fact questions on exams but I'm perfectly happy getting a B. I'm also perfectly happy learning the material in a way I find manageable, instead of memorizing it.
I hope you can work your way back up!!! Good luck
