Rewrite your solutions to any two of the problems on the first three Homeworks. Make sure you address whatever issues led me to take off points the first time (ask me if you're not sure why I did!). Give me a complete new write-up of each proof -- don't just make new marks on your old one, and don't hand in partial proofs. Also, hand in the original version with it, so I know how many points to add to your score.
If you wish to use a problem (or two) from HW3 for this assignment, that is OK. I will do my best to grade HW3 and return it to you by Monday, October 3.
Please email me if you have any questions about this!
