I'm keeping a notebook for the solutions of the problems, leaving each page of the notebook for each problem. I write detailed answers for each problem, as well as hints and notes for my personal understanding.

I'm thinking of a strategy to keep in mind for the real PGRE testing. For example, this strategy will apply for each problem during the test:

- 1) Attempt to solve problem within 1 minute or so. If get nowhere, then go to #2. If you need a little bit more time with certainty in solving it, just solve it asap.

2) Check if dimensional analysis or some type of elmination can occur. If not, go to #3.

3) Skip

3a) Skip for good, and cross out problem. (In case it's something you won't be able to solve)

3b) Skip for coming back to it later, and circle problem (In case you have more time)
