Free mock test for JEE Mains chapter wise
Every ViJEEta chapter test is a 25-question adaptive test that starts at moderate difficulty and adjusts after every answer you save. Unlike a fixed PDF worksheet, it finds the exact difficulty band where your understanding breaks down, certifies chapter mastery up to 1.00, and queues twin questions for every mistake.
Starts easy, then finds your level
Each test draws from the calibrated pool for that chapter (1,53,429 JEE and 30,542 NEET items), stepping up when you answer right and probing subtopic prerequisites when you miss.
Whole chapter or single subtopic
Test an entire chapter to certify exam readiness (0.80+), or pick any subtopic inside a chapter to isolate a single weak concept before Sunday's part test.
Worked solutions & twin practice
After Question 25, every item shows your choice, the official key, the step-by-step solution, and a one-click button to practise a twin question on the same concept.
