OK, I am a tutor, so I'm biased- but stay in school, anyway! You hate chemistry? Do you want to grow hydroponically some day? That's chemistry! Math is a real drag, but you will use some of it, at least, in everyday life. It also teaches your mind to be able to solve problems. You also will need to know metrics (I learned mine by how many ounces in a kilo and how many grams in an ounce- dope was a great motivator). Biology- understanding how a plant or an animal (like humans) works is good to know. My dear, high school IS a bitch,( but college is a whole 'nother story! )Yet in the long run, it is better to put up with all the BS and seemingly pointless classes. The real world is tough and unless you have at least a high school diploma, you life will be tougher than it needs to be. I went to a continuation school and it was the best thing that happened to me when I was a rather troubled teen. The teachers there actually cared! Please don't give up on your education just because you have some "less than excellent" teachers. Look into the night school, see if your school has a tutoring program and join a study group. By the way, I'm old enough to be your Grandma and I smoke every day! Second time around in college (good connections there), I wrote almost every paper stoned and graduated with honors! LOL
