Cigarette smoke contains stimulants and does not "relax" you; rather it satisfies your addiction which gives the illusion of relaxing while it is only squelching an anxiety which wouldn't be there to begin with.

When I applied Harvard was the only school that required Calculus, the others only required 6 credits of college level math. I think you need to take it in college as only those credits will count for pre-requisite courses. Good luck
