Undergraduate / MIT essay about my biggest challenge [4]

Question: Tell us about the most significant challenge you have faced or something that didn't go according to plan. How did you manage the situation?

"You will not be allowed to resume until all your fees are paid and that's final. There is nothing I can do about that. Now leave my office". The accountant's statement cut through me like a scythe; I was devastated. For me, that marked the beginning or one of the darkest periods of my life.

It was my first day back at school for my 11th grade and I was very enthusiastic about returning to school. However, to my utter dismay, on arrival at the school, I was denied entry. I knew my fees had not been paid, but I never anticipated the drastic measure taken by the school to enforce its policy. As I reluctantly trudged back to the car, I tried to prepare myself mentally for what I imagined would be a bleak next few weeks for me.

When i got back home, my first reaction was to try to blame someone, but I had a rethink and decided it would be futile. Armed with copies of the schemes or work and my textbooks, I tried my best to study the topics currently being taught in school. When I returned to school three weeks later, I had to parry a lot of questions from concerned teachers and friends as I did not want to reveal the reason for my absence. Eventually, I was able to settle in, catch up with my mates and I ended up coming first in my class at the end of the term.

Please help me critique.thanks!
