Homework 7, etc.

• Homework 7 has been posted.  It is due Monday, April 8.
• Homework 6 has been graded.  Marks are in your Subversion directory.  A solution will be posted Monday.
• Mid-term estimated grades have been sent to the registrar.  They don't count for anything official; they are a way to let you know how you are doing. If you are considering withdrawing from the class, the CAS deadline is Friday, April 5.
• The course information is inconsistent on the date of the second midterm.  It will be on April 10, not April 15.
