I have it do hard Leetcode problems and then read the code and have it explain parts I don't understand.

And how do you know if the explanation is correct? I mean, explaining something like leet code that has a lot of background available in CS books and courses is probably going to be correct, but yet, you cannot be sure.

I know enough about algorithms and computer science to tell most of the time.
