CAT QA Explainer | Algebra | Quadratic Equations | Discriminant | Roots of an equation
Quadratic Equations are a favorite of the CAT QA. Each year you get two to three questions from this area. Another low hanging fruit that students miss in Algebra over arcane shortcuts.
CAT QA Explainer – Discriminant
This is Set-39 of 100 LRDI Challenge Series. In this we have discussed a past year #CAT Question based on Caselets.
We have asked a question at the end of the video, Try solving it and us know your answer in the comment Section.

CAT QA Explainer | Indices Surds Logarithms | Combo Quesitons | Additional Topics
In the Concluding CAT QA Explainer for Indices Surds and Logarithms, we look at combination questions – use of more than one area from the QA Section. We look at how to extend what we learned

CAT QA Explainer | Indices Surds Logarithms | Logarithm Properties
Logarithms are the favorite sub topic from Indices-Surds-Logarithms Triad. In this CAT QA Explainer session, we look at how basic questions from Logarithms break the tension during the QA section of CAT. Usually these questions can be solved with minimal manipulations or using options.
CAT QA Explainer – Logarithms
CAT QA Explainer | Indices Surds Logarithms | Surds – Approximation | Rationalization | Using Options
Surds are a favorite of CAT and IIFT Papers. In this CAT QA Explainer session we look at basic concepts of Surds and how to use options and approximate the values to solve the questions in a breeze.
CAT QA Explainer – Surds
CAT QA Explainer | Indices Surds Logarithms | Properties of Indices | Algebra | Numbers
In this session of CAT QA Explainers, we look at basic properties of Indices that can be used to solve questions from CAT, XAT and IIFT Papers. Master these easy properties before you waste your time on remainders, last digit and factorials area of Numbers.

CAT QA Explainer | Indices Surds Logarithms | Indices – Basic Powers | Powers of 2,3,5 and 7
Students fret over what to study for CAT QA especially Numbers and Algebra. Indices, Surds and Logarithms are what they should study – along with their manipulations. These are low hanging fruits that make up around 15% of the CAT QA Section. Way more than last digits, remainders, probability, etc.
