AP classes
I took a ton of AP classes while I was in high school and it really helped. That is because of Mizzou’s application of the AP scores to fulfill requirements. If you are in high school and deciding whether or not to take the AP exam at the end of the year, do it! Yes it is expensive, but it is so worth it. The test costs about $82, but if it gets you out of English 1000 or another class, it could equate to hundreds of dollars. If you take the class, take the test. It seems silly to put yourself through all the work of taking a demanding course when you could get something really good in the end.
