If you have 479 tokens, you can keep the QCs of roughtly 10 tests (it costs 45 tokens to keep QCs in lab 3, don't know for later tests of lab 4). You don't have many tokens, so take a look at the comments that mention the hardest tests. I've read that the hardest tests are 26, 31, 38, 42, 48 (the hardest seems to be 42 and 48). But I've spent 45 tokens to keep my QCs on test 23, because my car was infected and "exploded" in the last corner, so I didn't finish first and I was really annoyed to lose all the QCs. But I have around 6000 tokens and remember that you can win quite a lot of tokens by doing as many races as possible in the Renault Trezor championship.
