Tips I learned with keys and tokens:

1. If paying to keep QC's, remember the value of the key used. For example, I am starting test 50. Someone noted below that they passed it spending 200 tokens to keep QC's. But, he/she neglected to consider the 200 token value of the 4 keys they used. That's 400 tokens total. Still better than auto pass for 750 tokens. However, if I only needed a few QC's, and it costs 90 tokens to auto pass, then auto pass is the better deal (50 token value key, and 50 tokens to keep QC's). On the other hand, if you have more than enough time left in the event, then the key doesn't have value, so playing once more and keeping QC's for 50 tokens is more with it than the 90 token auto pass.

2. Before going to bed, check how much it costs to buy a set of keys. Say there is 1 hour left before key regen, and it costs 90 tokens (the price drop is not linear with time left, unfortunately), but you want to go to sleep, think of it as 90 tokens for a set of keys (which would cost 150 tokens when you're cramming before the end). Good deal. Buy, play, sleep. Of course, if you have excess time to finish the event, ignore this and just sleep and play the next day.
