hi guys
have just dualled my kensai to a mage, and took advantage of the scroll-write magic-get experience trick [after temporarily disbanding my party].
Anyway, worked a treat, had been collecting scrolls just for this purpose, and got up to 8th level; however, on each level up, although the amount of spells I could learn each day increased, I didn't actually get any new spells [other than the ones I had just writen to my spell book].
Is this usual? Do mages not automatically get access to new spells, or do they always have to learn them from scrolls?
Thanks in advance
b/
no new mage spells when dualling...?
Yes, mages must learn all their spells (except the 2 they choose at level 1) from scrolls, you only get some at character creation in BG2 because you start as a 7th level mage and it is assumed you learned some spells in BG1 
There are three kinds of people that no one understands: geniuses, madmen and guys that mumble.
