CLASS MEMORIZE/FORGET SKILLS DURING SWITCH? [RMVX]

What I am trying to accomplish through use of a common event (I don't know scripting) is a way to, whenever a class is changed by a character, that the new classes skills are added to the skill list while the old ones are forgotten. I've tried using conditional branches for each level that adds a skill, and this (despite making perfect sense) does not work. I've also tried memorizing my hero level and then switching to 1 and back using a variable to add the skills that way, but no dice. Does anyone know, without scripts, how something like this can be done? It really makes no sense why Enterbrain would choose not to include this ability in the editor while it appeared in Rm2k3...

EDIT: I've tested the exact same method in Rm2k3, and it works perfectly fine. Is there a bug in RMVX that may cause it to function differently?

Sorry, I have no clue how to work with scripts. All I see is a bunch of jibberish, with no clear indication of what goes where and what must be changed.

Is there any way to simply do this using switches/variables/etc in a common event?

I mean, there has to be some logical way to set it up in some way similar to:

If Alignment Var is 1 or more
Message: You are now aligned with the Light.
Change Class
Forget all skills
If Hero Level Var is ????
Add all skills up to said level
or
If Align Var is -1 or less
Message: You are now aligned with the Dark.
Change Class
Forget all skills
If Hero Level Var is ????
Add all skills up to said level

EDIT: I've found what the problem was with my method. It seems that I was unable to save the amount I had stored in a variable, and that I needed to add a sort of patch script to my game. Now, with a few readjustments to what I had already written, it works fine.
