Best rank you can get without using tokens or non-R&D free upgrades is 3-5-3-4, Upgrade to 0-1-0-0 right after completing first test, then use the first R&D free upgrade given in second to get 0-2-0-0. Upgrade to 3-2-3-2 before receiving second upgrade, then use this and the further received upgrades to get 3-5-3-4, by buying remaining upgrades with credits.
