Dear
Welcome to HCM
We understand your concerns
I went through your details. I suggest you not to worry much. You must understand that memory power never goes down for a healthy young individual. But
anxiety, low interest level, low self confidence etc can reduce concentration and create memory problem.
Active reading is your solution. Effective learning is the key. Reading two hours continuously without understanding anything or understanding 10% of what you read is waste of time and energy. Studying for 30 minutes and understanding 20 minute stuff is real reading.
How to achieve this? There are several techniques. Search internet and you shall get many.
1. Be serious and passionate about your studies. Don;t just study to satisfy somebody and to pass exams. Learn for your future.
2. Change subjects every half an hour.
This is a beginning. More studying (effective learning) techniques are available. You can post a direct question to me in this website. Include every detail as much as you can. I am sure that the techniques should be a success.
Hope this answers your query. Available for further clarifications.
Good luck.
