no, marks are assigned randomly to levequests at the leve reset. In otherwords, if you change classes to pick up the leves, the same rewards are offered. Also, the same rewards are not offered for the same levequest each reset. I have not yet seen a pattern for rewards, so I think they are randomly assigned.

If you have a class within range of the leve, then there is a chance that leves will offer marks as a reward for classes withing range. What the other poster said about rank 15 is actually not true. You can start getting marks as rewards from the rank 10 leves, but since you need to do so few of them before they aren't worth it any more, the chance is rare that you will find one that offers marks.
