will you help me get my driver's license?

ok, i turned 17 in december. i got my drivers permit on march 22, 2008. and i started driving school on march 17, 2008. ive been on all my driving lessons with my instructor except for one. i had to cancel my last appointment because i lost my permit and i am not allowed to drive without it. so since september, ive been driving my moms car and it seems like im not getting any better. my mom had an extended trailblazer so its pretty big. i would drive the car my grandfather got me but i crashed it when i drove without my mom knowing. i would like to get my license in the next 2 months. can you give me some tips on how to accomplish my goal?
