how can i get good marks in bsc chem hons my subsidry sub is phy and math and extra hindi from magdh univercity and i am now in 1st year

you have to work hard to get good marks , in chemistry you need to do more practice write and make diagrams and for whatever your are learning , if you write while learning then it will help you to give more concerntaton on your study

My experience is that the difficulty can be resolved by paying attention to the problems part especially in Physical Chemistry.Don't leave any chapter just because it is difficult.Always rely on a good text and never on guide-books .
