I’ve finally gotten through working out the mid-semester grade estimates, and I’ve added them to the Blackboard site for the course. You should see a column called “MidSem”, which contains a number on a 4-point scale. The idea is that anything above 3.67 is an A, above 3.33 is an A-, above 3.00 is a B+, and so forth.
I computed these based on the assumption that there were only 5 assignments (one score dropped), and that the score on the final is the same as that on the midterm.
I will post information about the BUCLD extra credit assignment within a couple of days, which is something you can do to substitute in for the next lowest homework score.
Also: please double-check that there isn’t something unexpected there, e.g., a homework you gave me that didn’t get recorded, or a typo in a score.
