I went to school early, around 6:20 AM, because my class was at 7 AM. But when I arrived at school, Sir suddenly announced in the group chat that class would start at 7:30 AM. While waiting, we went to the food court to eat. Then it suddenly started raining heavily, and since I didn’t bring a jacket, I got wet and cold when we walked back to the building—along with some of my classmates. While waiting, I took some pictures so I’d have something to put in my diary.
When class finally started around 8 AM, our lesson was about data encryption. It was really confusing because we had to convert characters into bits, change them into different bit lengths (64, 32, 56, 48, etc.), and follow several rounds of permutations. If even one bit is wrong, the entire process becomes wrong. It was dizzying and overwhelming. I really hope I pass that subject.
