The lectures covered everything up to chapter 3 and some other stuff putterman thought was important. However, both midterms and the final could be ACED if you had just focused on chapter 2 alone... and that's 80% of the entire grade. For 115a, make sure you know everything about chapter 2 in griffith's intro to quant mech, try to do every problem in the chapter. Putterman's tests are tricky, and the math involved always look overly complicated at first; he expect you to apply the fundamentals and simplify the problems.
