In inorganic chemistry first you need to divide the syllabus in two parts one is conceptual and other is memory based the conceptual part is the structure of the compounds hybridisation theories of structure of compounds and the memory based part is the reactions and the properties of compounds.

For the first part you can understand the topic well and and practice new questions and consider the exceptions well also if you look at the previous years questions of the competitive exams then you can understand it some compounds which are also in the syllabus of the exams are structures therefore you need to focus more on that part on the second part that is memory based in it to remember each and everything but the problem lies when students don't have proper knowledge of the syllabus therefore you should have Chrisp and clear knowledge of the syllabus and only prepare from the syllabus try to revise daily.
