procedural question: how do you incorporate an exp section into a digital PT on this site?

(Really glad that it's possible to do all tests digitally here, but other sites (khan, powerscore) include an experimental section. Despite having far fewer PT available overall theirs is a much cleaner way to PT digitally.)

How do people go about incorporating an exp section here, under timed constraints? I'm asking at a technical level, pretty much, since there's no pause option or breaks during timed tests on here.

Do you exit the PT, go to an already opened section in a new window, then navigate back into the actual PT? Seems like an inefficient hassle, not to mention not simulating test day very well at all.

Love 7sage but not sure how to approach this. Thanks!!

Why foolproof 1-35 in particular? I will have had about 3 months study leading up to Nov administration, and have done most logic games sections 19 - 70s. I haven't however touched a pre-19 PT. I'm foolproofing some of the middle ones now, 30s - 60s, but wondering if this is like..wrong... Does FP need to be done with PT 1-35 or is that just a suggestion so as not to burn thru sections of what would otherwise be better to use for full timed PTs (like I've done, admittedly stupidly)?
