A letter to University

I was asked to write a letter and within that letter state my reasons to why I have retaken English and Math twice. I am applied to university and little while ago I received a letter, asking me to provide a reason. So far, I have made many attempts to write a somewhat decent and comprehensibly letter. I am fairly bad at writing letters because I haven't wrote any. Please, read my letter and give me any feedbacks or corrections you may have.

With this letter I would like to explain why I’ve attempted to retake MHF-4UI and ENG-4UI. During my senior years in high school, my attendance was poor, and it was largely because I spent my time studying metaphysics. Moreover, I was 16 and I became increasing perplexed by many conflicting situations that filled me with bewilderment, and it was to do with my own existence. I always had a keen interest towards philosophy of existentialism and I decided to pursue the tail that took two years, till I came to a realization that constituted a fulfilling achievement. I consider those years as bleak point of my life, but I overcame the existential obstacles and in the process, I learned to live life passionately and sincerely.

After, I decided to continue my education in (the school that i am attending and finishing up my last course). This time, I attended regularly, did the work, and earned a good grade. I kept it brief because I do not wish to bore you with my life story, this letter is a mere generalization of the two years that I spent studying metaphysics. I hope there is enough detail to help you to understand, and if you require any further detail-I will be more than happy to provide it.

Thank you for considering my application, and look forward to hearing from you.

Yours sincerely,
my name
