Dear Lybrate user. I can understand. Physical exercise, outdoor games, entertainment, socializing coupled with systematic life style improves your memory and mind power. Vegetables, fruits and nuts are perfect for memory. Brain games like sudoku and jigsaw puzzles helps too. Avocados, Beetroots, Blueberries, Broccoli. Celery, Coconut Oil, Dark Chocolate etc are good for improving concentration and memory. I suggest online education counseling. Take care.
