Does anyone know how best to prepare for this midterm? I have Harrison and I'm really worried! I feel like he is going to throw some tricks in there, and I've heard his midterms aren't easy.

I had Harrison last fall term for orgo, and found the midterm to be very straightforward. The MC is easy if you read the textbook, and he tests on small details for MC. The short answers were pretty easy as well but they all have multiple parts to them. I found his exam to much harder than the midterm. I personally recommend reading the textbook for all the chapters being tested and doing the practice problems in the textbook as well. I never focused on the lecture slides at all.

Edit: Also, he didn't throw in any tricks for our midterm, but for the exam he did. Might be different this year though.
