CSC151.01 2007S, Class 03: Working in DrScheme

Admin:
* EC: Thursday, 11 a.m., Johanna Meehan on vocation (or lack thereof).
* EC: Thursday, 4:15 p.m., John David Stone on the game of life.
* Read Beginning Scheme for Friday 
  (perhaps in advance of doing the assignment).
* Homework 2 is available, and due Friday.
  * Form groups today!
* I anticipate finishing grading HW1 tomorrow.

Overview:
* Wrap up the MathLAN lab.
* Do DrScheme lab.
* Reflect

-----

Questions:
* I'm so awesome, I finished the lab before class started.  What should
  I do?
  * Find a partner, and start the HW.
* I feel stupid.  I see people around me finishing the second lab, 
  and I haven't even started it.  Help!
  * Different people progress at different speeds.
  * Early success or difficulty is a poor predictor for overall
    success in the class.

Reflections:
* How do you know the square root computation is correct?
