Reminders:

  • Despite of an earlier announcement, I will hold an instructor’s informal session tomorrow in RAS 213, to give more review on the midterm 4 material. For those who can attend, please mark your calendar. Bring your questions to the session.
  • Schedule for the remainder of the semester:
    • Wed: More Q & A on unit 4. Course instructor Survey
    • Fri: Review for the final.
    • Monday (May 5): 12-1pm (place to be announced). Review for the final.
    • Friday (May 9) 12:15 to 1:15 Q & A session. (place to be announced)
  • This week is the time to finalize TT-records of the semester.  It is each student’s responsibility to check his/her TT-record carefully. Let me know if there are errors and/or concerns. Monday (May 5) 5pm is the deadline for complaints on your pre-final exam TT-records. Complaints will not be accepted beyond this deadline.
