If you're in advanced placement classes, you're intelligent. I doubt the weed has anything to do with it to be honest. Especially just once a week. Very few people do better in school while high or whilst daydreaming of getting high. I hate to say this and sound like I'm stereotyping.. but I am.

How many true stoners ((the guys that are stoned as fuck everyday)) do you see when you look around in your smart-kid classes? I would imagine somewhere between 0 and 0.

Now what about how many social stoners ((like yourself)) do you see when you look around your smat-kid classes? Maybe.. 2-3 out of the entire class. At least, that's how it was for me. Then I went to 'bad-kid school' and almost every one of those kids smoked near every day. And they were stupid.

Marijuana doesn't kill brain-cells. But, that doesn't mean it won't fuck up your education like any other mind altering drug can.

And yes of course I realize video games and all the other dumb shit that has the exact same effects on schooling.

Just don't get to the point where you'd rather get stoned then do your homework. A hell of alot of people do.
