The skills page shows the calculations on what the percentages are needed to skill up. It can become a little tedious, trying to calculate what pecentage you need. I got this table from one of my guild mates, hopefully it will work for you:

To Skill Up Ultra Rare:

10 rare or 5 rare ex = 100% (skill up from level 1 to level 2)

6 rare ex + 3 rare = 100% (skill up from level 2 to level 3)

10 rare ex = 100% (skill up from level 3 to level 4)

5 rare ex skill 2 + 5 rare ex = 100% (skill up from level 4 to level 5)

10 rare ex skill 2 = 100% (skill up from level 5 to level 6)

2 rare ex skill 4 + 3 rare ex skill 3 + 5 rare ex skill 2 = 100% (skill up from level 6 to level 7)

10 rare ex skill 3 or 8 rare ex skill 4 = 100% (skill up from level 7 to level 8)

7 rare ex skill 4 + 2 rare ex skill 3 + 1 rare ex skill 2 = 100% (skill up from level 8 to level 9)

10 rare ex skill 4 = 100% (skill up from level 9 to level 10)

Disclaimer: I have not tested the above table, so I cannot verify or guarantee accuracy. But it looks right at first glance. Hope this helps.
