Just as a PSA, don't do leves at 25 when you're 24. There's a minor penalty for doing leves you're not in the 0-4/5-9 level range of, and you'll generally get better EXP just by doing the 20 leves with +4 bonus.
In fact, do every leve at the +4 bonus: they're not that much more difficult when you're at that level range and the exp reward skyrockets.
