Set Theory and Real Number System
No batch is running yet. Tell us when you’d attend and we’ll open one. You’ll see the time and the price before you pay.
Is this the one you’re stuck on?
Everything a batch would cover. Scan the five parts, then read into the one that’s yours.
Sets
- representation of a set
- different types of sets
- subset
- proper subset
- power set
- universal set
- Venn diagram
Operations on Sets
- complement of a set
- symmetric difference of sets
- Venn diagrams of set operations
- intervals as a subset of set R
- cardinal number of a set
Inequalities
- values of x squared from given values of x
- values of 1 by x from given values of x
- sign scheme method
Modulus of Real Numbers
- graph of the modulus function
- absolute value as a square root function
- modulus of any expression
Inequalities Involving Modulus
- modulus of addition and subtraction
You don’t have to just listen.
“Sir, I don’t understand why we used this equation here.”
“Let’s go back one step. Look at what’s rotating.”
Ask your question. Stop the teacher. Ask them to explain it another way.

Tell us what you need and we’ll open a new batch to suit it.
A teacher who doesn’t fully own a chapter teaches it half-convincingly, and you absorb the hesitation.
Learn it from someone who owns it, and you absorb their certainty instead.Usually taken before this one
