Okay - you'll still make a lot of progress in the 3x3 portion so that gives you another 4-5 weeks which puts you right about on track for your return to school. Really glad this worked out for you, I knew that it would but it's always satisfying to hear someone really enthused and happy about their progress and what they've attained.
The idea is to get an idea of your tolerances so you know what kind of work capacity you have - it sounds like there's a good chance you can tolerate more but it's really hard to know for sure. It kind of depends on how you set your weights - generally the best barometer is your second run through (sequential so next off-season or some such wouldn't qualify) because you know yourself a bit better and with relevant previous maxes in all lifts you are really able to dial in the weights. Ideally, you want both week 3 and 4 to be new records so both are in excess of previous bests and it's a lot easier to do this after you are already up to level.
That said, if you really pushed yourself you know that you can be more aggressive next time in setting the weights. In being conservative (which is essential for a first run through because reaping 80% is a lot better than 10% if you botch the weights) people generally wind up with a semi-loading phase where they are really only breaking records in week 4. Two weeks of this pace with relevant maxes is a different story (ask anyone here) but assuming you were to tolerate a 2 week heavy loading period well with this volume you'd gradually start phasing out the 1x5 workouts and transitioning them into 5x5's. Maybe not all at once but several sets at a time (say 2 ramped sets of 5 and then 3x5 with the top weight) and then later M/F become mirrors of each other with 5x5 each although some people might still rachet one of the days down a bit at first to a lower weight. Since the squat is the biggest driver it's the one you want to be fairly conservative with. I mean, obviously the current volume works pretty well for you so it's not like it's so far off that you need to rachet everything. Basically, just something to keep in mind over time and the whole reason a training log is valuable (plus, your body will gradually adapt to higher workloads over time so you if you continue to train seriously over extended periods this is something that you will eventually have to account for).
Anyway, keep us updated on the 3x3 portion and how it goes. You should be really happy by the time you get to campus as a lot of people really enjoy pushing the weight up here after the volume phase.
