GABA? or glutamate?

Not enough?! So much so for that 20% and yet it turned out like crap. 24/7 been sitting there with backaches and gym-skipping..? Disappointing betuL.. I really need to stimulate my brain cells before the finals. Long term memory, need GABA ( am i right?! or glutamate..?) still cant get over the test i had this morning. confused with the facts.. Damn smart. spot question. those skipped ones came out. stupefied...
