Hermione's Education Crisis

My take on why Hermione agreed to give up on a couple electives after 3rd year. A stressed out Hermione has the reality of the wizarding world revealed to her by the most unlikely of sources. Short standalone one-shot or a fairly inconsequential occurrence that is briefly mentioned in my new fic called Obligatory Marriage Law Fic. 3rd year, no pairings, could be canon possibly.
