<p>Currently I am a freshman and have taken pre-ib bio. It was the hardest course I've taken and consistently getting B+ with my highest quarter grade is 89.81(A--------) One issue I have with this course is the chemicals in biochemistry(Such as NADH, NADP) I am extremely terrible with chemicals and chemistry. Will IB bio and AP bio have a lot of remembering chemicals or is it jus pre-ib that has this to cover all the general stuff while the higher courses will go deeper into areas of biology such as ecosystem and environmental intereaction ?</p>
