Is it a bad thing to take on level courses in high school?

My goodness your smart. Just be sure to not get to weighed down to where you just want to quit. Dont over do or under do.... if you feel pressured then its probably time to ease down and take a few less AP courses. Be sure you know what each college requires for you to attend. Its never too early to check that. Some colleges on their web sites tell how many credits you have to have in certain courses in order to attend. You are on your way! wow CONGRATS...
