I am gonna reply anyway. I respect and agree the fact, that you shouldn't use magic for everything. But, then again apart from messing with free will, its all fair.
I'll post a spell from my Book of Shadows, I think i took it from everythingunderthemoon site.
It helps me to calm down before a lesson for sure,
Tools : White candle,charge it with your favorite oil. Sandalwood stick.
"With this fire igniting my memory,
set this knowledge a blaze in me,
everything i learn today shall i retain,
every word, every diagram, shall stain in my brain,
and as i gaze upon the flame,
may the godesses help me know what,
i need to soak into my brain,
so, mote it be"
(Say it 3 times, let the candle burn out)
Focus on the candle and imagine a blue color light around your head opening it up to new knowledge.
Hope it helps!:)xx
