[Optional - if you're interested in CNNs and PyTorch - otherwise work on your final projects.]
Do the Neural Networks and Training a classifier parts of the "60 minute blitz" tutorial.
Save the code in a python file, and follow the instructions to train the CNN on the CIFAR-10 dataset. If you have an account on gattaca, work there -- training will be faster on the GPU :). Instead of copying and pasting the code as you go, you can also skip to the end of the cifar10 tutorial and download the python source.
You can work in pairs or alone.
