Is it okay to forget whatever we study?

Is it okay to forget whatever we study ??
It’s so tough to remember all drugs name in pharmacology and this and that action and so many…
P.s : feel like haven’t studied anything at all , like everything is new .

It may seem superficial to you if I say " dont worry". Look at the exam process logically. You dont get filling the blanks in neet exam, it’s a multiple choice which means the options are there, you just ha e to jog your memory rather than be solely dependent on it for an answer. So dont worry. At this point it may seem you cant retain anything but the human mind is very powerful. Under pressure it performs and how.
Have faith in yourself.
