This is my last year of school, and i am having lots of troubles because i found some gaps in my instruction, due to the fact that i didn't get anything to study from.I've always been very good in scientific subjects but this year i'm shitting bricks, sorry for any grammar mistakes, but i'm terrified(and foreign).
Please, i need help.
