Don't bother reviewing anything. Realize that vet school is all about quantity over quality. Perhaps 30% of what you cover during your four years in school will have any clinical relevance. The rest is pretty much filler. Much of what you will "learn" can be regurgitated on a test and then forgotten. Two suggestions though: if an instructor tells you to try to understand overarching concepts and not worry about details, you'd best try to memorize as much trivia from as many Power Point slides as you can. Sort of a corollary to that suggestion: if you want to prepare for vet school lectures, browse the internet for a detailed set of Power Point slides on any random topic: finance, aviation, cooking, art, history, auto mechanics--whatever. Memorize them. The next day, pick another topic and do the same, then return to another set of slides on the first topic. Repeat for a week or two. Multiply both the number of topics and the length of study by five or six and you will get a pretty good idea of your first couple of years of vet school.
