You feel hard to remember.
You think for a while that when you grow up. Your entire sibling are educated will have very good education and status. You will feel small at that time but time will be a passed.
Pray 5 times and pray to Allah Pak for yourself.
The other thing which I can suggest that start Hifz-e-Quran, this will increase your memory and Inshallah you can study.
