I find the easiest thing to do is max the first few cars in D, C, and B classes, as they do not need to be pro-level to finish mastery. For D class, it is up through the F-150, C class is through the Ford Focus, and C Class is the Survolt and Aston Martin Coupe. Look at the rating required for challenge 15, and pro it to that point, but save the rest of your cards. Then just work on the cars you use most often. I maxpro'ed the Veneno, as it was my go-to S class car for a while, and the final mastery event is great for farming credits. Im sitting at 151 licenses, and I have some more cars of the aforementioned to complete to the challenge 15 point, but it should get me to at least 175. Beyond that, just use your cards strategically and hoard mid-tech like a miser. (Sidenote, it'll take awhile, but I would suggest buying at least one car for every type of rare engine that you can, that way you can keep from filling your pro card storage. (I have 3 F12 engines, 2 rotary engines, an i6, and 7 electric engines because I don't have anything to use them in.))
