If I am being honest with myself, what I write down I tend not to refer back to, I rely on the areas I have hi-lighted.

However, I think the value I find in writing things down physically has to do with cementing the structure/other bits of information into my short term memory (which may be why I don't need to refer back to what I have written down as much)

I was stuck between A and B. I wound up choosing B for the right reason but eliminating A for the wrong reason.

I eliminated A because I mis-read the AC. I read the AC A to mean "only 1/20 income-tax advisors will prepare a correct income-tax return" which is the opposite of its true meaning.

I think that is a reminder for myself that when I am stuck with 2 ACs to really be certain I am reading the ACs correctly!

This might be really silly but I have never seen the options to hi-light or underline on this platform, how can I enable those options here?

The advice I have read:

Always do questions 1 - 12 first, then 20 - 25/26, then do 13 - 19 (they usually put the hardest ones in there).

Also, skip the conform to principle questions, those waste so much time and are meant to lower the curve. If you run out of time, guess B on those. (last 5, D)

You want to maximize your score, you'd accomplish this by answering the most amount of questions as possible!

Precisely because the amount of coffee drinkers could be much larger than the amount of insomniacs (making it unlikely that he is an extreme insomniac).
