Sab ko meri taraf se ASSALAM-o-ALIKUM

Mujhe aap sab se 1 help chahiye thi. Mere 2nd year mein 748 marks aye thay federal board se. Mein kuch subject improve karna chahta hun 2nd year ke. Mujhe koi yeh bata sakta he k agar mein kisi subject ko improve kar raha hun aur second time mere marks pehle wale se kam aa jayein to kya mere pehle wala marks lage ge ya phr yehi wale lage gein?
