theoritical subjects=subjects without stuffs to solve like numericals, algorithms dsa to solve etc.

i understand, verify and revise theory but end up getting only MAX 40 marks in those subjects.

but i consistently get 55-65 in numerical subjects.

one thing that i think is hitting my grades hard could be the books that i follow. i don’t follow pulchowk notes or system inception books to learn rather follow some other textbooks(not the ones mentioned in reference books either).

i feel that these teachers are unable to know if that answer is correct if the answer that i wrote doesn’t fall according to the solution sheet they have and cut my marks.

while i know there is more value of the learning that i do rather than grades. but it hurts me to get 40/80 even after working my ass off and even knowing that i learnt everything properly.

anyone here who gets good grades in theory subjects knows what should i write in those to get good marks?

is there anything that i need to change in my study that is hurting my grades?
