# Basic Concept Videos

These are a new set of basic videos.
These are helpful for your Intermediate Microeconomic Theory Course. This course is taught at Delhi University in two semesters. In semester 3, Intermediate Microeconomics I and in Semester 4, Intermediate Microeconomics II.
We have also added few videos on Introductory Econometrics, taught in semester 4 of Delhi University, Economics H. We will be adding more as we move on.
If you read Varian, Intermediate Microeconomics, along side these videos, all your basics will be cleared. We have also mentioned Chapter numbers along side, using them, read the text alongside. Similarly, for Econometrics Course, please read Gujarati side by side, along with these videos. We hope they will be helpful to you, whether you are preparing for Semester Exams, MA Economics Entrance, UGC NET Economics or Indian Economic Services.
