It is important to research various colleges as you begin to narrow down your choices. Most importantly, you want to find out about their admissions requirements, deadlines, course offerings, costs, and financial aid programs. Every college has a website that is kept up to date. Use it. If you do not see information on the college website, contact the college and they will be able to answer your questions.
In addition to individual college websites, below are two links that are excellent resources.
