I'm currently on test #3/37 but I spend about 2millions credits on upgrades at begining to MAX and keep few the most expensive upgrades for Free Upgrade when I win test and pickup rewards. Only 2-3 tests were hard so I pay 50 tokens per race to keep collected QC and continue to next tests. For now my AF10 is at rank 1777 and I make some upgrades to Pro 3-1-3-0 but now I need about 40 V8's to max pro. I hope few I'll get in advanced kit box.
