Lab 1 and 2 is very easy. And you will probably finish the lab early because you have to wait 1+ or 2+ days to unlock next lab.

But that's the thing people fell for it---it's easy R&D.

It all starts lab 3 and 4. You will be surprised that you can only finish lab 3 just one or four hours befor the lab 4 unlocked. If you did fully max with fully pro the car might able to finish early--or skilled player, of course.

And that is not the end of story really. You have to play 13+ hours everyday for the Lab 3. Of course, except top-ish player who can rank wihin 1,000 in most of TLE. Or spent bunch of tokens.

And then Lab 4... That's more crazy. You probably have to play 18+ hours everyday for the Lab 4. With almost fully max and pro the car. If you couldn't upgrade a lot(but at least you need car for 0404 3030-ish), you should have bunch of tokens--so you should spend token to collect QCs on test 45 to 49.
