biochem will not help raise your score (thats for sure)... but it will help your DAT-review process go smoother.... because alot of the general chem calculations you did in biochem (i.e henderson hasselbalch, pHs, etc) you need to know them for GC, so this is kind of a review.... Plus the extra knowledge you'll gain about glycolysis is cool, most of it won't be tested on in the DAT, but when you review biochemistry for DAT and how basic it is, you'll fly right through it
