Beginner to Powerlifting

Hey guys,
My name is Jancarlo Perez, I'm 19 years old, I am a sophomore at MIT, and I am also an aspiring powerlifter/Olympic weightlifter. For the time being, my emphasis will mostly be on powerlifting.

After two months of consistent training, this is where I stand on the bench, deadlift, and squat:
Bench- 315
Deadlift- 335
Squat- NA (haven't tried maxing out)

These are the goals that I wish to achieve by the end of next semester:
Bench- 405
Deadlift- 450
Squat- >405

These are the goals that I wish to achieve by the end 0f this semester:
Bench- 335
Deadlift- 380
Squat->315.

Hopefully I can meet these goals- either way, I am going to give my best.

My current plan:
I recently started this 5-day a week program-
Monday- Rest
Tuesday- Squat, Deadlift, and Ab work.
Wednesday-Rest
Thursday- Bench, and other chest and back exercises such as weighted dips/pullups, rows, etc.
Friday- Light workout, usually just isolate arms and work on weak areas (currently my shoulder muscles).
Saturday-Squat, Deadlift, and Ab work.
Sunday- Bench, and other chest/back exercises.

Any advice/critique would be appreciated! Thanks in advance.
