HOW TO CALCULATE EXP:
this is how to calculate how much you get:
opponents Lv divide by 2
10/2=5
7/2=3.5
this is how much your pokemon will need:
if your pokemon is Lv10 then you pokemon will need 20 exp
if your pokemon is Lv7 then your pokemon will need 14 exp
how it works is(if you haven't found out yet) take your level and times it by 2
10x2=20
7x2=14
