Train/test accuracy mismatch

Good points! The other thing that just happened recently is that the course staff has fixed some problems with the tests in the notebook: the tests were missing some errors. It’s worth updating to the new notebook and rerunning all the tests. To do this, just open the Logistic Regression notebook and you’ll get the new version. Then you need to use the procedure on the FAQ Thread to update the new notebook with your previously completed work.
