Academic expectations

Tried my best to study hard during the previous term, really expected to do well, but my hopes were crushed when I saw my results. Felt like I did not deserve the grades I received, as I put in a lot of effort.
I started studying a week before the exams, had planned to study with my friends, and lock in, but obstacles came in the way and disrupted the study timings, which affected me quite badly. However, I persevered and studied for 14hours straight the day before the exam and felt proud of myself.
But I did not do well, still, but at least I did not fail.
