Learn it from the person who wrote it.

Every chapter, bench and problem on this site was built by him, by a mind set on making students actually understand physics. A session is the same physics, with discussion and live guidance — someone watching your working and telling you where it went wrong.

What moves the rate: the course and the level you are working at — a board-level hour and a JEE-Advanced hour are not the same hour. You will be told the figure for your case before anything is booked — there is nothing to pay to ask.

Why this exists
Depth, without the race.
Clarity is the method.
Your work, made to count.

An engineer turned physicist — he has stood on both sides of the choice these students are making. An M.Sc from IIT Madras, a joint doctorate from Dublin City University, Ireland and MUT, Poland, and teaching here since returning. One person writes and builds every page of this site.

Students arrive under two different pressures. In India the year is spent racing, and depth is the first thing cut. On an AP timetable the constraint is time — an idea has to arrive quickly, and be seen rather than narrated. Both get the same answer: the idea shown before it is stated, and nothing left as a formula to memorise.

Clarity is what is promised here. The marks that follow are yours — and every page is built so the hours you put in land.

All of that is written out on this site — thirty chapters, the benches, the banks — and a whole chapter of it is open before you book anything. See what is free →
How an hour runs

You bring the working. He reads it.

A session is not a lecture repeated at you. The reading and the drilling happen on the site between sessions, so the live hour goes where a video cannot: to the place your reasoning breaks.

Before
You send the problem
A photograph of your attempt, a paper you scored badly in, or a chapter you cannot get moving. He reads it before the call, so the hour does not start from zero.
First minutes
You explain it back
You talk him through your reasoning out loud. Most of the time the mistake surfaces here, in your own sentences, before he has said anything.
The hour
The bench is open
The same interactive benches on this site are on screen. You change a number and watch the answer move, instead of being told which formula to trust.
After
A named next step
Which sections to read, which bank questions to work, and what you should be able to do by the next session. Not “revise more”.
Three shapes

Pick the commitment, not the package.

All three are the same hourly rate. The difference is how much of the syllabus is his responsibility and how much is yours.

01
A single session one hour
One topic, one blocker. You bring the question you are stuck on and leave with the method, not the answer. Nothing follows it unless you ask — plenty of students take one hour on rotation or electrostatics and never need a second.
One chapter deep Doubt clearing A paper post-mortem
“His solution walkthroughs stop me getting stuck on similar problems.”
Jyothi · AP Physics C · 2025
02
Exam sprint six to eight weeks
The run-up to the paper. Twice a week, past-paper pace, and the weak chapters drilled until they stop costing marks. The syllabus is already yours — this is about converting what you know into a score under a clock.
Twice a week Timed papers Mistake triage
“In barely six weeks he gave me so much clarity on the topics I was weak in.”
Nischay · BITSAT · 2024
03
The long run where most students are
Two years for JEE, a year for AP, or foundation physics from grade 7–8. Weekly, whole syllabus, built from the ground up — and the reason most of the reviews below run across three or four school years with the same student.
Weekly Whole syllabus Grade 7 upward
“He devised a proper strategy that helped me secure a good rank in the IISER (IAT) entrance.”

Set by what the student needs, not by a package. You pay for hours — no bundles, no lock-in, no minimum term. The reading, drilling and revision happen between sessions, so the live hour goes to the hard parts.

The site itself is free — every chapter, every bank, every sim, no account. Coaching is the only thing on this site that costs money, and it is billed by the hour. The reading and drilling between sessions is what makes an hour worth paying for; it is not a substitute for the hour, and the hour does not replace it.
