Week of Test 2!

It's mid March, and you know what that means.....
Time for the 2nd set of midterms! Three in one week, as per usual.
I am really nervous because I've already had two tests this week that haven't gone as well as they should have. I'm hoping this test will go better than the other two.
I know this test is going to be on proofs, but I'm not sure if big O proofs are included as well or not.

I'm glad we can use cheat sheets again, but still a bit nervous for how that will affect the level of difficulty of the test itself.
I looked over the notes on proofs today, briefly, but I feel like proofs are something you can't truly study for. You can memorize the proof structure, and I feel I've done that, but for the proofs themselves, in the words of the student I talked to who got 90% last semester, "you just need to know how to prove stuff." Which makes sense. The only problem is, I'm not the best at proving stuff.
I guess now is the chance to change that.
