Extenuating circumstance?

Due to medical reasons(chicken pox), The ministry of education board gave me a 14 day quarantine period. As a result, I couldn’t write my 11th Grade Finals exam. I wasn’t given a retest to compensate for my Final Exam. My overall percentage dropped down drastically as my overall percentage was calculated without my 11th Final exam. The Final Exam comprised of 50% of the overall grade.

I wanted to enquire if this counts as an extenuating circumstance and if yes, how lenient will the admission councilors be?

Yes it’s an extenuating circumstance but how much a college will take that under consideration is anyone’s guess.

Have a realistic list of match and safety schools that reflects your record as is.
