Grade level is the another option to fight, to gain your personal Grade Level (not the personal Arena level which is currently at 10).

Usually at the last week before the new version, at the Arena main screen you'll notice a shining blue arrow located at the top right. Click on it and fight.

Unlike the normal arena, you can use as many active skills as you like (still will deplete Battle score), but at the result menu, as long as you cleared it you'll gain 40% exp. Reach 100% to get a Grade level up and get the specific rewards stated above.
