Dear Aksa,
Entire syllabus is important in s and p-block elements. Please go through the chapter notes, textbook questions, live test series, model tests, and chapter tests to make the concepts more clear.
For this log on to www.topperlearning.com
Go through the properties of both s and p block elements and do comparative study. Properties are mostly asked.
