The Temple of Knowledge, or schooling as some call it, is essentially how you "buy stats" from the game. You can complete each one only once, and they can take several days to complete, better schooling taking longer. Each "reset" that occurs at 12:00 AM game time will deduct a day from your time left, even if you bought the schooling only minutes before reset.
Whether schooling is worth taking or not will change as the game progresses. Early in the game money will be scarce, and as a result some of the schooling is not worth it. As the game progresses, and money is more readily available, more schooling becomes worth taking, but as that occurs, some of the early schooling will become a waste of time. Overall, decide for yourself if the schooling you are looking at is worth it or not.
