    • When we released Scheme, the order of Problems 4 & 5 were switched, and one of the Scheme tests was in the wrong place. If you downloaded the project before Wednesday 4/4 @ 1:15 AM, you will have to re-download the entire project. Copy and paste and code you wrote into the new folder and copy any questions you unlocked from the tests folder over except for 04.py and 05.py. If you wrote custom tests in tests.scm, copy ONLY those tests over (do not copy and paste the entire file). Sorry for the trouble.
