December 2006 Newsletter is out

Thanksgiving is over... Every year I swear I won't overindulge, and every year I end up over-turkeyed, over-pied, and sprawled out on the couch. This year was no different in that regard. Finals are almost here too, and that's more pressure than I care for -- just like last year.

What is different, though, is a new look for College-Cram. Acting on your many suggestions, we've reorganized the subject pages to reflect the Learn, Practice, and Review approach and made it easier to find relevant articles. We also gave the overall layout a fresher look. I hope you enjoy it!
