Maybe, if I spend the whole of the summer studying, I won't die of exhaustion before I can take my OWLs.
Ancient Runes - 3 hours, Saturdays & Sundays
Arithmancy - 3 hours, Saturdays & Sundays

Charms - 3 hours, Mondays, Wednesdays & Fridays.
Defense Against the Dark Arts - 3 hours, Tuesdays, Thursdays & Sundays
Herbology - 3 hours, Mondays, Wednesdays & Fridays
