How to Study Physics Wallah Lectures for JEE (Without Drowning in Three-Hour Videos)

Published 2026-10-23 · Francesco Masciopinto

Physics Wallah's YouTube channels are one of the most popular free resources for JEE preparation. The lectures are long, energetic, and packed with concepts and solved problems. That's the strength — and the trap. Many aspirants watch hours of lectures every day, feel productive, and still freeze in mock tests because watching is not the same as solving.

This guide covers how to study Physics Wallah lectures for JEE so the hours turn into marks: planning by chapter, note-taking that fits long videos, solving immediately after watching, and a revision system you can sustain until the exam.

The core problem: input vs output

A typical lecture might be two to three hours and cover a chunk of a chapter with theory, examples, and tricks. If you watch one such lecture daily and don't solve, you collect explanations without building speed or accuracy.

A healthier balance for most aspirants is something like:

Activity	Share of study time (rough guide)
Watching lectures	~30–40%
Solving problems (DPPs, module, PYQs)	~40–50%
Revision (notes, formulas, flashcards)	~15–20%

Adjust for your stage: early in preparation you may watch more; closer to the exam, solving and revision should dominate.

Plan by chapter, not by video

Lectures for one chapter can span many videos. Plan at chapter level:

CHAPTER PLAN — Rotational Motion
Lectures:    L1–L6 (approx. 14 hrs total)
Target:      finish lectures in 7 days
Daily:       1 lecture (~2–2.5 hrs) + solve DPP/practice same day
Day 8:       chapter PYQ set (JEE Main + Advanced level as per goal)
Day 9:       mistake review + formula sheet finalised

Writing the plan stops the endless "one more video" pattern and builds problem-solving into each day.

Watching a long lecture efficiently

Use 1× for new, difficult concepts; 1.25–1.5× for familiar parts or recap sections.
Split long videos into blocks. Watch in 40–50 minute chunks with short breaks.
Pause before solved examples. Try the question yourself first, even for two minutes. Then watch the solution.
Skip what you already know only if you can genuinely solve it. Be honest.

Notes that work for JEE

Long lectures produce long notes. Aim for three compact outputs instead of copying everything:

1. Concept notes with timestamps

[00:42:10] Moment of inertia — parallel axis theorem
  I = I_cm + M d²
  Valid for: any axis parallel to an axis through COM
  Common trap: d measured from COM axis, not from any axis
[01:05:30] Perpendicular axis theorem
  I_z = I_x + I_y  — ONLY for planar (lamina) bodies
  Trap: don't use for 3D bodies

The trap line is gold for JEE, where many questions test exactly these conditions.

2. A formula sheet per chapter

Quantity	Formula	Condition / note
Torque	τ = r × F	Vector; direction by right-hand rule
Angular momentum	L = Iω	About a fixed axis or the COM
Rolling without slipping	v = ωR	Contact point at rest instantaneously
Rotational KE	½ I ω²	Add ½ M v² for rolling bodies

Keep the sheet to one or two pages. Rewrite it from memory at the end of the chapter and compare.

3. A question-type list

Teachers often say things like "this type comes often" or "standard question." Note the type, not just the answer:

QUESTION TYPES — Rotational Motion
- Rolling on incline: find acceleration (various bodies)  [L3 @ 1:12:00]
- Angular momentum conservation: person on rotating platform [L5 @ 0:38:20]
- Toppling vs sliding of block                              [L6 @ 1:40:00]

Solve immediately after watching

This is the most important habit. After each lecture:

Solve the related practice problems the same day — DPP-style sheets, module, or textbook questions.
Attempt without looking at notes first. Check notes only when stuck.
Mark each question: ✓ solved, ~ solved with help, ✗ couldn't solve.
Rewatch only the segment behind ✗ and ~ questions, using your timestamps.

A mistake log

Every wrong answer in practice or a mock should go into a log:

Date	Chapter	Question source	Mistake type	Fix
12 Nov	Rotation	PYQ	Used perpendicular axis theorem on 3D body	Check "planar only" condition
13 Nov	Electrostatics	DPP	Sign error in potential	Write sign convention first

Mistake types usually fall into a few groups: concept gap, formula condition, calculation error, misreading. Review the log weekly; it often tells you more than another lecture would.

Revision: spaced and active

Flashcards for formulas, conditions, and traps. Review them over days and weeks.
Formula sheet from memory once a week per chapter studied.
Mixed problem sets from several chapters, so you practise identifying which concept a question needs.
Regular mock tests with the mistake log afterward.

WEEKLY RHYTHM (example)
Mon–Sat:  lectures + same-day practice
Sun:      mock test or mixed set → mistake log → formula sheet recall

Balancing Physics, Chemistry, and Maths

Long physics lectures can crowd out other subjects. Rotate daily or plan fixed slots so each subject gets regular practice. Chemistry often benefits from shorter, more frequent revision sessions; maths needs daily problem practice.

Common mistakes

Watching without solving. Feels productive; doesn't build exam skill.
Copying everything the teacher writes. Long notes are hard to revise.
Skipping PYQs. Previous-year questions show the level and style of the exam.
No revision system. Chapters done in month two fade by month six without spacing.
Comparing hours watched. Compare questions solved and mistakes fixed instead.

Navigate long lectures faster

The hardest part of long JEE lectures is finding the exact segment you need again. SummarizAI is a Chrome extension that adds a summary, chapters, chat, and Study flashcards to the YouTube watch page, so you can jump to a concept or solved example and turn formulas and traps into cards. The free plan works as a student trial. The problem-solving is still yours.

Frequently asked questions

Are free Physics Wallah YouTube lectures enough for JEE?

Many aspirants use them successfully, but lectures are only part of preparation. Practice, PYQs, and mocks matter as much.

Should I watch at 2× speed?

Usually not for new concepts. Moderate speed-up for familiar sections is fine if you still understand and can solve.

How long should I spend on one lecture?

Often the lecture length plus roughly the same time or more for practice and notes.

What if I fall behind the lecture schedule?

Prioritise practice and PYQs for chapters already watched rather than rushing through more videos.

Do I need separate notes if the teacher provides PDFs?

Use provided notes as a base, and add your own traps, question types, and timestamps.
