what do i need to study for english 10

I came to canada as an international student when i was 15 year old
sadlly, Ive never tried memorizing grammar and vocabulary during the year >.<
but i spent 100% of my free time with canadian frineds to talk about girls and stuff
now i ve just passed an ESL reading exam and i got grade 6 reading level there xD
then my teacher said i gotta take regular english 10 in order to graduate ..

here is a simple question guys

what kind of vocabulary and grammar do i need to study ?

kk thanks guys
peace
