What is the fastest way to level up in MechQuest

I usually do the order 66 thing or the giant spider at the university.

Hazza73 here, the easiest way to level up is by turning scale fights in assault mecha off, and typing in 10708710. it gives you some amount of exp between 200-300. if you're a star captain you can put Xtreme difficulty on and get about 440 exp. hope this helps!
