Hello

For attempting any type of mcqs you should follow excluding other options this is possible when you had multiple revisions of that subject

And inorganic chemistry has everything to learn and remember so for that you should read them again and again and try to make some mnemonics for easy recall and learn them again and again before exams

This well help you to exclude all the wrong options and then you can score well

And try to learn by writing that again and again

Hope this helps

All the best
