Probability for GATE CS

Translate the wording into events before calculating. Exact dice, Bayes and expectation examples show how to build the denominator and avoid the standard independence trap.

Linear Algebra for GATE CS

Reduce matrices cleanly, classify Ax=b by ranks, and turn eigenvalue properties into fast calculations. Each result is checked against an independent property.

Permutations and Combinations for GATE CS: Counting Questions Solved with a Repeatable Method

One repeatable method (choose, arrange, subtract) applied to 20 GATE-style counting problems, with the four-question decision procedure that replaces formula memorisation for permutations and combinations in GATE CS.

Set theory and relations: closures, equivalence and partial orders explained

Relations trip up more GATE aspirants than sets do. This guide builds from basic set operations to the properties that matter, reflexive, symmetric and transitive, then shows how closures, equivalence relations and partial orders get tested.

Combinational circuits: multiplexers, decoders and adders explained

A combinational circuit's output depends only on its current inputs, with no stored state. This guide works through the building blocks GATE keeps testing, multiplexers, decoders, encoders and adders, and shows how a single MUX can implement any logic function.
