Hello dear ,

to prepare for Inorganic chemistry , just read NCERT books . NCERT has lots of information which most of the students generally miss out in case of not reading them.In inorganic chemistry, you should study periodic table and chemical bonding very throughly. They contain all the concepts of inorganic chemistry and majority of the questions are asked from these topics. Practice a lot of questions on chemical bonding.Make your own notebook in which there are only chemical reactions. inorganic is moderately tough but as not as physical chemistry.

Hope this helps !!
