OG does allow you to do randomly-created problem sets in their online software, but you can't choose the problems yourself. So if you want to do a set that has pre-chosen questions in it (whether ours or your own), you've got to do a little work up front to set everything up.
This is what I do. I bought some little sticky notes that are just little strips, not full pieces of note paper. (You can also cut down larger stickies.) Then I use them to mark the pages for a problem set and I number the notes (1, 2, 3, etc) so that I can flip quickly to the next one.
If the problem is around the outside edges of the page, I place the sticky note so that it's actually touching the problem. If not, I put a second sticky note on that page placed directly on the problem I'm supposed to do. (If I have two on the same page, then I write (a) and (b) so that I know the order.)
Once it's all set up, boom, I just look for the next-numbered sticky note and flip right there - takes 1 second. (Also, because I'm super anal, as I take the sticky notes off, I line them up on my desk, so I can glance quickly to see what the next number should be, in case I forget.)
I could imagine that someone else would do something like this:
- place the 10 stickies (for 10 problems) sticking out of the book running top to bottom, so you just go to the next "highest" sticky left
- place a second sticky on each page directly on the problem you want to do
That's probably easier than my method but uses more stickies. I'm cheap.
I also don't use our GMAT Navigator program
while I'm doing the problems. I just note down my answer on my scrap paper, hit the lap button on my timer, and move on to the next problem. That takes about the same time it would take on screen to click "next" and "confirm." Afterwards, I have my answers and my time, and I enter them manually into Navigator.
Agreed that there's tons of stuff to learn / do / remember. Let us know if you have any other questions!
