The class average was B- and median was B+, just like on test 1, so again great job overall.
To encourage exams as a learning experience you can earn back the greater of +3 or 15% of the points you missed. If you are below the A, B, C range of proficiency (i.e. below 70, since we are on a 10 point scale), you'll have more work to do, hence the possible greater number of points. 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!
