Everyone has had memorable memories, be it happy or sad. for me, the memory of a bad grade reminds me forever. The day before the test, I went out all day and forgot to study. The next morning, when it was time for the test in class, I tried to think and think that I could only do one third of the test. as a result, I got poor grades. I regretted it so much, since that test was so important that it also affected my results quite a bit. I will remember that sad memory, turning it into a motivation to try harder.
