Physics with Deepak Kumar
I teach students to understand the physics behind the equations, build a problem-solving method they can rely on, and walk into demanding international examinations knowing what to do with an unfamiliar question.
Current focus
IB Physics · AP Physics
A Level, WACE and Singapore O Level are also taught, on the courses page.
Who this is for
“Honestly, I’m just confused. I need someone to help me make sense of physics from the ground up.”
“I know the formulas. I just don’t know which one to use or how I’m supposed to know.”
“I understand the topic, but when the question changes slightly, I don’t know how to apply what I’ve learned.”
“I understand the concepts. I just want harder problems to build speed, accuracy, and confidence.”
The method
01
Identify what is given, what is being asked, and any conditions or constraints that define the situation.
02
Turn the words into Physics using diagrams, free-body diagrams, graphs, ray diagrams, circuits, or other useful representations.
03
Identify the physical principle, then choose the law or equation that actually fits the situation—not simply one containing familiar variables.
04
Work systematically through the unknowns, checking signs, units, directions, assumptions, and whether the final answer makes physical sense.
05
Repeat the framework until individual concepts become secure, then progress to complex problems combining multiple concepts or topics.
Current curriculum focus
Each syllabus is treated on its own terms: its command language, its assessment structure and its standard for a strong answer.
Standard and Higher Level, taught around the three papers and the internal assessment.
Algebra-based and calculus-based courses, with attention to the reasoning the free-response section asks for.
Free resources
Three things I give my own students: find your gaps, learn to read the question, then use the formula sheet properly. Each one fixes a specific reason marks get lost.
KNOW · Free · IB Physics
A complete SL + HL revision tracker designed to help you see exactly where you stand. Every concept is broken down across Recall, Apply and Transfer, so you can tell the difference between simply recognising a topic and actually being able to use it in unfamiliar exam questions.
DECODE · Free · IB Physics
IB Physics questions often hide the most important information in the wording. The Exam Decoder helps you identify what terms like constant, elastic, negligible, isolated, uniform, or equilibrium are really telling you about the physics before you even start calculating.
REFERENCE · Free · IB Physics
The official data booklet gives you the equations. This one helps you understand and use them. The Data Booklet on Steroids adds clear variable definitions, useful relationships, conditions, diagrams, reminders, and extra formulas that make the booklet far more practical during revision and problem solving.
Problem sets
The harder questions I use with students aiming at the top grades, with solutions that show the decisions rather than only the algebra.
42 questions
$10
Paper 1A style multiple choice questions built around conceptual traps, proportional reasoning, equation selection and interpretation rather than recall.
27 problems
$15
Twenty-seven extended problems that connect topics, ask for multi-step reasoning, calculation, interpretation and written physics. Quality over quantity.
YouTube
Problem solving, exam strategy and physics explained without the unnecessary nonsense.

The teacher
I’ve been teaching physics since 2019, and STUCK IN PHYSICS is my attempt to build the kind of physics learning environment I wish more students had access to.
I teach students to see the physical situation before reaching for an equation. That approach was shaped by years of teaching IB, AP, A Level, WACE and Singapore O Level Physics — and this is where I turn it into lessons, resources and a method you can use when a question is unfamiliar.

Being stuck in physics is usually a sign of a missing physical picture, not a missing formula. Here is how that happens and what to do about it.
Problem solving · Study approach · 7 min read
A practical reading process for exam questions, from command terms to hidden assumptions, with worked examples.
Exam preparation · Exam technique · 6 min read
Paper 1 is not a test of speed alone. A short set of habits will recover marks that most students lose to careless reading.
