i gota go against the grain here guys, i would of done better if i hadnt of got into the weed about a year before i took my exams. dont go a bite my head off for saying that, but for me personally i guess i became to focused on how i was gonna get stonned that evening, instead of concentrating on doing my homework on that evening. it wasnt the weed rotting my brain making me stupid, its was my obsession with the weed. me personally anyway
