I use 1:24 interval videos to stay focused.

I've been having serious problem concentrating lately. I thought it might have to do with the fact that I'm not doing the questions timed, and found playing this video while working on questions kind of helpful.

It's a 1:30 interval timer, but the first beep is at 1:24, which is convenient.

Doing timed sections over and over again helps with this. You become more automatic, like a machine, over time. After a while you stop thinking so much about the fact that you are “doing a test” and become absorbed in the material. Granted I still get distracted almost every section but this is natural. The best tip that I have is, if you can’t focus on the question you are reading, skip to the next question. Keep skipping questions until it clicks and you “forget” that you are distracted. I’ve heard of high level scorers who will skip five or six questions in a row.
