My Teaching Style

For best comprehension, I like to divide my session into two parts:

Teaching Using Digitized Content

I use my own training content which has been specially prepared keeping the needs of students in mind. I focus upon clearing the basics of the subject first before moving on. Detailed explanations provided in a easy to understand manner forms the key to understanding.

Chemistry Quizzes

At the end of each session I go over the quizzes on the topic with the student which ensures correct assimilation by the student and any gaps in knowledge that may be there are clarified. I also provide Chemistry Quizzes for Organic Chemistry Exam which students can attempt in their own time and discuss with me during the sessions. Please feel free to Contact Me for any clarifications.

A sample presentation and its associated quiz is given below. Please feel free to go over the presentation and attempt the quiz.

Organic Chemistry Study Topics

The study topics covered by me for Organic Chemistry at College Level have been given out below.

Tips for Learning Organic Chemistry

To succeed in Organic Chemisry, you need a well organized approach. Remember the key to success in Organic Chemistry lies in understanding of the topics in detail. Some study tips for Organic Chemistry are as follows:-

  • Over 10 Million organic Compounds exist. You cannot possibly remember all of them. However once you know the basics of how they are formed, believe me, you will be able to understand them all.
  • Organic Chemistry is rational, systematic, highly organized and not at all difficult to understand. There is no need to be scared of Organic Chemistry - Organize yourself and you can master it.
  • Work on problems. More you work yourself, more intricacies you will understand. Lots of quizzes are available on this website - attempt them all. Click here to go to online courses
  • Study actively- with pen and paper. Draw structures for molecules mentioned by name. Write complete reactions during the practice with reagents.
  • Prepare the summary / flash cards for each topic - they help you to refresh your memory instantly.
  • Ask questions to your teacher. For this you need to study the topic one night before. Review your topics every day. Do not leave them for the penultimate day
  •  Each chapter requires the knowledge of previous ones to understand it fully. It is preferable to go in a sequence and not jump chapters.
  • Master periodic properties of elements so that you can understand organic mechanisms very well.
