Also i believe the ranks at which you can get marks as reward for a class, equals the ranks at which you can obtain higher rank leves. which would be 13,23, etc. (i think? :p)
At any rate, if you can get the rank 30's to give you marks instead its a better deal for you anyway, since higher rank tends to give a lot more marks as reward. ~
