Heyyy nightowl, I'm kinda in the same boat as you but have decided on a strategy.
I wanted to get through the OChem, GChem, and Phsyics 1001 books in about 21 days so I had decided to do 150 questions or so each day....but I found that impossible and counter-productive. So now I took my range of 150 questions that I have allocated and simply do every third problem. I think these basic problems are good to stimulate and slightly reinforce material --> and then after that just move onto practice tests.
So yeah...set a range like 150 questions....and do every third question(that's what they say in the EK Home Study Schedule) and you'll have only 50 to do but you'll cover a good span of topic. Their difficulty spread w/ each subject is enough that you'll get at least 1 easy, medium, hard question even if you're going by threes
weeeeeeee
