"So, Do you remember how to solve a quadratic equation by factoring? It's been a while, right! I can understand.
Let me revise the concept for you. It is fairly simple and expects not much. It boils down to simple division/multiplication/addition/subtraction. Yes, as simple as that. If you could figure out which two numbers multiply to a 6 and add up to a 5, for example, then you already know what it takes to factor a quadratic! I know, you have got it, that, 3 and 2 multiply to a 6 and add up to a 5. Great! So, let us now see how this ability to rightly find the two numbers that multiply to a given number and add up to a given number helps us factor a quadratic."

my conversation with a student usually sounds something like the above.

Students make notes in the class of their learnings. They practice some assigned questions after every content class, clarify their doubts before connecting for the next content class. They go through assessments periodically and have thorough feedback on a regular basis. They complete their preparation with mock-tests and review sessions and be ready for the actual test

"Sir, Thanks a lot. It could not have been possible without your guidance. I made it. I am so happy and overwhelmed. Thanks again sir."

is what students who have given all that it takes to score higher report to me after their test

"Sir, I missed it. I am sorry. You have been very helpful, though."

is what students who miss scoring higher for a variety of reasons report to me after their test

Finally, what makes me a great teacher or for that matter, anyone a great teacher, is a willingness and deliberate effort to make the delivery of lessons - creative, effective, and efficient day after day.

Great Tutor!

Raj has been an excellent tutor for my child. He adjusts the pace and content to match the child's aptitude and progress, which is exactly what we had been looking for. He also has a great online instruction setup with appropriate feedback and highly responsive to queries and questions. Thank you Raj and Prepcool! Would 100% recommend Raj!

A truly awesome experience!

Amazing teaching. I've been prepping for the SATs with Sir's help and I've developed so much from where I started. I would recommend 100%, any time, any day!

Great SAT Class! Fully Recommend

I liked this class a lot because of how they would teach and make sure it is interactive so one doesn't get bored by a lecture. Plus they are most of the time in contact even sometimes at unreasonable times which is very helpful. I recommend for other students as well to take these classes for whatever test you need help with.

Gmat quant.

Mr. Raj is patient, helpful, knowledgable,experienced, and enthusiastic person. What I really like about his teaching style is that he has a clear teaching And studying plan and he keeps following my progress and keeps introducing challenged questions that covers Many topics and skills. He is a very good tutor who knows what you need and what you have to do to improve your score.

Great tutor who knows what he’s teaching? Look no more!

Where do I begin with Mr. Raj? He is a very professional, knowledgeable tutor who knows all the ins and outs of the GMAT. What I love about him the most is that he’s very flexible with the student. He’ll meet you where your level is at and doesn’t mind spending as much time with you as possible. Mr. Raj is also funny and compassionate which I believe are both as equally important as being a great teacher. I’ve seen MAJOR progress since I started working with him in March. Best mentor I’ve had hands down!
