Hello Aspirant,

See it is a normal human process that you can never learn 100% so try to learn 100% so that you can learn at least 90% of it very thoroughly and even if you forget 10-20% of it then not to worry because you are still remembering at least 70% of the syllabus or content that you have consumed.

Best learning process follows the rule of 3-4-7 whatever topic you read, read the same topic again after 3 days then after 4 days and then after 7 days and that topic will be stored in your permanent memory so you can hardly forget that topic.

I would recommend you to practice this technique to increase your memory efficiency.

I hope this information helps you.

Good Luck!!
