is it good if i solve the problems, parallel to reading theory??? or should i solve it separately after reading entire theory?? especially for inorganic?

It is better to go through the theory first and then solve the questions . BecauseIf you practise questions parallely you will know the topic from which the question belong and the theory is also recently studied , you will easily give the answer .The benefit of solving questions after completing theory is there will be miscellaneous questions just as in our exam .You can also identify your weak topics and can revise them .This will also make your revision easy .you will not need to focus on the whole chapter rather you can focus on your weak areas .....
