About the course

This course is for toppers and hard-working students who want to excel at school and do well in competitive exams like NEET. This is NOT an easy course. Students must be willing to study Biology for at least 4 hours every week. To do well in competitive exams like NEET, you must understand each concept deeply.

Why is this course?

In this course, you will get detailed concept videos on each topic in Std. 12 by expert teachers Prof. Paul Vinotha Rajan

A large number of practice questions with video solutions are included in each topic to help you check your understanding and master the topic.

What we offer?

In each lesson you will get classroom video lectures by Prof. Paul Vinotha Rajan, interactive concept lessons, practice exercises with video solutions and periodic tests.

Step by step, these videos and exercises will build your understanding of key ideas and you will learn how to apply them in various situations. Solved examples and video solutions will help you learn innovative techniques for problem solving.

What you have to do?

1. Each week you will have about 5 hours of work. You can do it anytime, but it would be ideal if you fix up a weekly schedule for this course.

2. It would be best to do the course over 2-3 days during the week. For each sitting, ensure that you have at least one hour of undisturbed time to see the videos and solve the exercise questions. Use headphones for listening to the videos.

3. Maintain a separate notebook for this course. Take notes when you see the videos. Solve the questions on the notebook and then enter your answers to check if they are correct. This is a serious course.

4. If you miss doing a lesson, try and catch up soon. While the content will be available for you to do anytime, we strongly recommend a disciplined approach where you complete each week’s lessons by the end of that week itself. Biology cannot be mastered in one day. To learn physics well, you need to learn, think and reflect every day.
