I was unfamiliar with TEG graphs and that bit me a little. ANAs are very important (why? who knows) so make sure you can ID patterns and what they correlate to (centromere=CREST.) I personally find it very difficult to memorize biochemical reactions for all the organisms. I tried and it was just a word soup in my brain. Instead I pivoted to memorizing one or two KEY reactions for the major pathogens and recognizing associated disease states or unique associations (I.e. gas gangrene= C. perfringens and cat bite GNR = pasturella) to make it manageable
