Today I am going to give a short tip to you all so listen carefully.
While studying a formula like the one of Pythagoras theorem or learning the periodic table in Science. It's very tiring and when I learned these I only remembered them during the test and after that, all gone!
Do you have this problem too? Well, if you have then I suggest you write the whole periodic table or any formula you want to learn and paste it simply at a place where you go to first in the morning.
For instance, If you go to your study room first, Paste the thing there and read it every morning and night and put it in a way that when you are passing by, you can read it again and again.
This way the thing will be in your mind forever with no stress on how to learn it! Problem solved. Right?
