^ yep, i agree with BaBeeLaiLai...it depends on your study/work habits and the course...i remember when i was back in high school, i took a psychology course and a sociology course over one summer...and i'm a procrastinator, so one night i was up finishing the final for psychology up until 3:30 am (and i worked on it from 10 am that morning!) and then i had a flight to catch that morning at 7 am...lol...that was terrible! but i got A's in both...so yeah...lol...
what course are you planning on taking?
