If you've ever done trig before, take the early completion course. You can get everything done in the first to weeks of school if you want. You don't have to go to class and you don't have to do math lab hours (which are TERRIBLE and so time consuming). Everything is online. If you do the homework and miss a question, you can use the "Help me solve this" and it will teach you how to do it. There are also videos that teach you about the different subjects if you need a refresher. Exams are just like the practice exams, just shorter. Be careful with computer math, a stray comma, period, number, anything will make the question WRONG. IF YOU HAVE TAKEN TRIG BEFORE, TAKE EARLY COMPLETION!
