Reminders:

  1. Schedule for the remainder of the semester:

a.       Wed: More Q & A on unit 4. Course instructor Survey

b.      Fri: Review for the final – I.

c.       Monday (May 11): 12-1pm (RLM5.104). Review for the final – II.

  1. Final (May 13) 2-5 pm. Wel 1.316
  2. The iq-record for the current semester ends last week. There are 6 iq-drops.
  3. It is each student’s responsibility to check his/her record carefully. Let Matt know if there are errors and/or concerns. Coming Friday (5/8) 5pm is the deadline for complaints on your pre-final Quest-records. Making sure that your Quest record is accurate before this deadline is one of the requirements needed to obtain the gp status. Complaints on pre-final Quest-records beyond this point will not be accepted.
