* Local names using let, letrec, let* and named let
* Variable-arity procedures

Computer Science Generalities
* Recursion (over lists, over trees, over vectors, using numbers)
* Tail recursion should be more efficient than direct recursion
* CS is fun, but can also be insanely complex and difficult
* Why and how to document your work.  (The Six P's)
* What abstract data types are
  * And some sample ones: Lists, Vectors, Queues, Stacks
* The general form of CGI
* Sorting and searching
  * Linear search
  * Binary search
  * Insertion sort
  * Selection sort
  * Merge sort
  * Quicksort
* Objects and records

Other Academic Skills
* Solve big problems by breaking it down into smaller problems
* Learn to keep problems on "the back burner" so that revelations can come to you at surprising times; Give your problems time
* Sometimes you need to be very formal and analytical, and being formal and analytical can force you to think differently.
* Group work
* Taking risks / Thinking on the fly

Morals
* Computers are sentient and malicious
* Don't give up
* Beating your head against the wall repeatedly gets old real quick.  Get help soon!
* There's more to life than *any of your courses* (but you can't use that as an excuse for most faculty)
* It's always possible to have fun, even when using cons

* Treat people well
* Thre's more to life than schoolwaork (or spelling)
* You can often have fun with what your doing, even if it's "incredibly difficult"
