How it works
Every test follows the same routine, so practice sessions build the habits you need in the exam hall.
Choose a chapter test, from Electric Charges and Fields to Semiconductor Electronics. Each one lists its topics, duration and marking up front.
Enter your name, read the rules and start. The test opens in fullscreen so nothing else competes for your attention.
Switching tabs, apps or leaving fullscreen earns a warning. Use all three and the next one submits your test.
See your score, accuracy and time, then walk through every question with the correct answer and a worked explanation.
Live tests
Short, focused tests you can finish in one sitting, each covering the core of one NCERT chapter.
Test 01Electrostatics
EasyCoulomb's law, electric field and flux, dipoles and Gauss's law applied to wires, sheets and shells.
Test 02Electrostatics
ModeratePotential due to point charges, equipotential surfaces, capacitor combinations, dielectrics and stored energy.
Test 03Current Electricity
ModerateDrift velocity, resistivity, cells and internal resistance, Kirchhoff's rules and the Wheatstone bridge.
Test 04Magnetism
ModerateMagnetic force on charges and wires, Biot–Savart and Ampère's laws, galvanometers and magnetic materials.
Test 05EMI and AC
HardFaraday's and Lenz's laws, inductance, LCR circuits, resonance, power factor, transformers and the EM spectrum.
Test 06Optics
HardMirrors, refraction, total internal reflection, lenses, prisms, microscopes and telescopes.
Fair-play mode
A score only means something when it reflects what you actually know. These rules apply from the moment you press start.
The test opens in fullscreen when you press start. Leaving fullscreen counts as a violation until you return.
Switching tabs, minimising the browser, opening another app or reloading the page is detected straight away.
Each violation shows a warning and is logged. Once all 3 are used, the next one submits the test with the answers you have saved.
Time keeps running while a warning is on screen. When it reaches zero, your test is submitted automatically.
Warning 2 of 3
You switched away from the test
The test tab was hidden. You have 1 warning left. After that, leaving the test again submits it automatically.

Question 4+4
A cell of emf 2 V and internal resistance 0.5 Ω is connected across 3.5 Ω. The terminal potential difference is:
1.75 V, your answer
I = E/(R + r) = 2/4 = 0.5 A, so V = E − Ir = 2 − 0.25 = 1.75 V.
Results
The scorecard opens the second you submit and stays saved on the Results page, so you can come back to it before the next test.
