What I heard is 46 and 47 are easy. 48 and 49 are flawless. For 48 someone posted below a strategy which will require 4 keys and 180 tokens to save collected QC'c for those 4 keys. Final AI being simple it should take one key.

So if you have some tokens to buy keys then go for it else it looks tough considering 3-5 keys per test. I generally buy keys after 2 hours which costs roughly 60-70 tokens.
