RPG MAKER 2003 CLASS SWITCHING TROUBLES

If you keep track of exp in a variable(Variable X), you can call on that variable at any time to bring the hero's exp back to it's proper value.

If RPGMaker resets your exp at the start of battle, then at some point after that you use the variable to set hero exp. Add exp by the amount stored in Variable X.

Is it changing exp in battle or outside of battle. I'm not sure if you can use Call Event command in battle. But, you could create a common event that resets exp to 0 by reducing exp by the amount of maximum possible exp. So if at max level exp gained is 100,000 you would start the event by reducing exp by that value. Now that exp is 0 you can use the add exp command to increase it by the true exp value stored in Variable X. (or you could put this block of code in every battle if you can't call on it)

So any time there is problem with exp not being right you can call that common event and set it straight.

That's just me thinking, all that stuff might be possible and might work. Might not. But that's what I'd try in your situation.
