You'd need to read it at least 20+ times before it starts to stick in your head.
Psychological pressure is enough for that, I remember that when there are remain five minutes to finish the exam, I forget all information.
It sounds funny, but that doesn't have to do with the pressure, it's called a the doorway effect, that there's every tendency a person will forget half of everything they've read once they pass through the door of an examination hall, compared to when they're in their reading room. It happens to almost every student, and humans will need to relax and think to remember what is been stored in the brain.
Also if you watch tiktok, the chances of you remembering 12 words drops significantly (no joke).
The world is losing brain powers from watching most of these contents for long time on the internet that's why many are afraid of the institution of AI. Many people are losing their brain easily these days.
Thank God, I have not download TikTok since it was Musical.ly.
Lol, you could count a few of your kind in the wide world.
