Description

If you are a student of Chemistry...

If you don't like chemistry, but you need to learn this topic just for the sake of exams...

If you know the concepts, but don't know how to do numericals on this topic....

Then this course is for you.

Each lecture includes the numericals or multiple-choice questions and lots of quiz questions.

The lectures are very small so that you don't get lost in the topic.

I hope you will enjoy.

Negative and positive comments, both are welcome. This will help me in improving the lectures.

Good luck...
