Hi,

For exam we should take every topic sincerely. Sine it is difficult to predict which paper will come easy or which will come difficult as the papers are confidential.

It also depend on individual how he takes the subject. If I found physics easy the paper will be easy for my on the other hand if for my friend physics is a difficult subject to understand the paper will be difficult. Usually a common perception is that physics and maths paper comes difficult ,Chemistry moderate or easy and biology easy.

Hope this helps.
