My Teaching Style

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

Learning Using Specially Created 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.

Solving problems based on topics covered. 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 are clarified. I also provide Chemistry Quizzes for AP Chemistry Exam which students can attempt in their own time and discuss with me during the sessions.


About AP Chemistry Exam

Advanced Placement Chemistry is a course and examination offered by the College Board as a part of the Advanced Placement Program to give American and Canadian high school students the opportunity to demonstrate their abilities and earn college-level credit.


AP Chemistry Grades

The Students scores on the free-response questions are combined with the results of the computer-scored multiple-choice questions; the weighted raw scores are summed to give a composite score. The composite score is then converted to a grade on a 5 point scale:

AP Grades Definition
5 Extremely Well Qualified
4 Well Qualified
3 Qualified
2 Possibly Qualified
1 No Recommendation
