Semi-class XP/Level Question

My apologies if this has been posted before. I did a search of the forums for "Semi-class", but I did not see this answer posted.

What is the XP needed per level for Semi-class? Is it different per Semi-class? Does the xp required for the next level scale up?

At this time, for the Semi-class I've taken, it seems to be 10,000 xp per level for the first four levels. However, while attempting to attain the 5th level for this semi-class, the normal xp needed/level seems to have changed (though not explicitly stated). It's alright if this is the expected behavior, I'm just curious.

The semi-class xp required should be:
1st level: +10,000 xp
2nd: +11,000 xp (21,000 total)
3rd: +12,000 xp (33,000 total)
4th: +13,000 xp (46,000 total)
5th: +14,000 xp (60,000 total)

Basically, they take up xp as if you are working for 11th to 15th level in normal classes.

Thank you for the information.

Can we maybe get that XP chart put into the description on semi-classes? Maybe have a sub-forum on the FAQ's forum for semi classes only, and have a general info page with the above XP stuff, and maybe some other info that pertains to all semi-clpasses, and then also move the individual semi-class threads into that sub-forum?
