Quick Guide

Revision Order

M1 → M2 → M4 → M3 → M5

High-Value Topics

DFA/NFA Construction, Regular Expressions, CFGs, PDA, Turing Machines, Decidability

Writing Strategy

Define → draw automaton → give formal definition + example

Before Exam

Practice DFA/NFA to RegEx conversions and CFG derivations from PYQs

Pro Tip: Always draw the state diagram neatly — a correct DFA with labeled transitions earns full marks even with minimal text.
