Math Practice and Puzzles Sites
Although it is not a drill and practice site as such, the first site I would like you
to visit, before you practice, is a site called:
"The Most Common Errors in Undergraduate Mathematics"
by Eric Schechter at
Vanderbilt University in Nashville, Tennessee. While much of the math described on this
page will be too advanced to understand right now, I think you will be surprised
at how some common math errors that we have discussed are still being made by
college students. Just skip the parts you don't understand (they will make good reading
in a couple of years so keep it bookmarked!) and focus on the parts you do
understand. Particularly interesting are the sections on sign errors, dimensional analysis (checking
your units), invisible parentheses, and undistributed cancellations.
