just began this one as my last asphalt moment revival

wanna ask: since 4 free upgrades are at 3,9,20,27, and the free upgrades at test 3 is best to use at 2nd level of nitro, are the rest 3 free upgrades can be spent at top speed's level 3, 4, 5? (i,e, we should be able to upgrade top speed to level 2 before test 009 right?)
