Most of the chapters we will study in Class 11 forms a base of what we will study in Class 12. Forming a good base in Class 11 is important for good marks Class 12 Boards.

 

In each chapter, we have divided it into two parts - Serial Order Wise and Concept Wise. 

Serial Order Wise is studying the chapter from the NCERT Book. This is useful when you want to look for a particular question or example.

Concept Wise is the Teachoo (टीचू) way of doing the chapter. First a topic is explained, and then their questions of that topic - from easy to difficult.

 

We suggest you do all the chapters from Concept Wise, so that your concepts are cleared. Which is important in competitive exams like JEE, GRE, GMAT as well as in Class 12.

 

In this class, the chapters and their topics include 

  1. Chapter 1 Sets – What are sets, Roster & Set-builder form, Types of sets - Empty Set, Equal set, Finite & Infinite sets, Subsets, Universal Set, Power Set, Intervals, Venn Diagrams, Operation of sets - Intersection, Union, Complement, Difference
