Welcome

If you are getting ready for calculus, at some point you may need to take a "Math Readiness Test" to qualify to enroll.  This blog and video podcast is just for you.  I will post a number of problems that I have been asked to solve that could be on this test.  It includes algebra, geometry, trigonometry, mathematical modeling, "word problems", logarithms, discrete mathematics, matrices, sequences and any sort of problem anyone starting Calculus should be familiar with.

Good luck!
