The class average was 82 and median was 88.5, so great job overall. If you are below the A, B, C range of proficiency (i.e. below 70, since we are on a 10 point scale) then come see me so that we can discuss strategies well before test 2. There are still plenty of opportunities to succeed in this class, and many of you are doing so already.
To encourage exams as a learning experience you can earn back the greater of +3 or 10% of the points you missed (with the caveat that the maximum possible grade will be capped at 103). To earn these points, you will turn in all 4 of the proofs on the test and correct any questions you did not receive full credit for. You may write directly on the test or attach your corrections. Regardless, you will turn in your test too.
I am happy to help in office hours. For example, you can work on these with me, or obtain my feedback on your draft responses.
