keep going and you will be given a score in the end.

if you want to focus on Statistical Learning, I can recommend Introduction to Statistical Learning Using R[1] by Prof. Hastie and Tibshirani.

I found the lectures entertaining and the exercises of a much lower quality. Not enough of them, shallow and ambiguously worded.

I got something like 90% on the edx MITx probability course and was barely getting 50% for the above mentioned Stanford stat learning course for the 5 weeks of it I completed. I mention the MIT course, (which I highly recommend fwiw) only to support my view that I don't think my experience is aptitude or workload related. But as ever YMMV.

I feel your pain. Have been using git-filters for this, specifically this repo: https://github.com/toobaz/ipynb_output_filter

It strips all notebook output from *.ipynb-files before commit.
