Challenge - Math

I love a challenge. I'm back in college after 15 years; it's been almost 18 years since I've taken a math class. I decided to find out where I fall in the scope so I can pick the right math class at a "doable" level.

I had 50 minutes to complete 30 problems, without a calculator but I could use pencil/paper. Each question was multiple choice(1 of 4 answers listed.) I've left the notations of the ones I actually did correctly.

If you'd like to see how you qualify, and for what class you would be suited if you were going to take one, feel free to take the test. I'll post the correct answers in a couple days, along with the class level in which you would be placed.

Go ahead, amuse yourself. 50 Minutes, no calculators, Go!!!
*hugs*
