“we averaged a 20% on our second midterm! I ended up scoring a 60%,”
This actually sounds very good to me. I have heard of similar grade averages in premed organic chemistry as well as a few other premed classes. If you keep getting at least twice the average on your tests you probably should consider yourself to be doing very well indeed. I am pretty sure that there are lots of doctor’s whose first B- was on premed organic chemistry as an undergrad. One daughter referred to organic chemistry as the most difficult B- that she ever had in her life.
