YOUR PREPARATION PRIORITIES

Draw the situation, state the principle and identify the unknown. Check the direction and units of the result before moving on.
Separate a memory gap from a reasoning gap. Use reaction conditions, structure and physical principles to explain why an answer fits.
Compare an algebraic, graphical or numerical approach before committing. Review the step where a correct method became an incorrect result.
INSIDE MYNDAQ
Read the explanation, ask the AI tutor for help and revisit the concept behind the mistake. Course counts below come from the live catalogue.
YOUR PRACTICE ROUTINE
Use a short diagnostic in each subject to identify a specific weakness. Keep separate notes for a missing concept, a misread condition and an avoidable calculation error.
Alternate concept-led work with mixed problems. For each question, name the principle or representation you will use before beginning the calculation.
Review a timed set before attempting another. Reconstruct the correct method and practise one related problem so the correction becomes usable.

The standard electrode potentials are E°(Fe3+/Fe2+) = +0.77 V and E°(Fe2+/Fe) = −0.44 V. The standard electrode potential E°(Fe3+/Fe) is:
For the cell reaction Zn(s) + Cu²⁺(aq) → Zn²⁺(aq) + Cu(s) at 298 K, E°cell = 1.10 V. The cell EMF when [Zn²⁺] = 1.0 M and [Cu²⁺] = 10⁻⁵ M is: (use 0.059 V for 2.303RT/F)
A student measures the length of a rod five times and gets the following readings: 4.2 cm, 4.3 cm, 4.1 cm, 4.2 cm, and 4.2 cm. What is the mean absolute error in the measurement?
Among the first-row transition elements (Sc to Zn), the element that shows the maximum number of oxidation states is:
If cos⁻¹(3/5) − sin⁻¹(4/5) = cos⁻¹(k), then the value of k is:

THE FACTS BEHIND THE TEST
JEE (Main) is the national entrance examination for B.E./B.Tech, B.Arch and B.Planning admission at NITs, IIITs and other centrally funded institutions in India, and the qualifier for JEE Advanced. Facts below are from the JEE (Main) 2026 Information Bulletin; the 2027 bulletin is not yet published.
2027 dates not yet notified
Dates and fees can change. Later source checks are dated beside the relevant fact; other facts retain the baseline review date. Confirm current details on the linked official page. Myndaq is not affiliated with the exam body.
75 questions for 300 marks: Physics, Chemistry and Mathematics with 25 questions each. In every subject Section A has 20 multiple-choice questions and Section B has 5 numerical-value questions. Each correct answer earns four marks, each wrong answer deducts one, and unattempted questions score zero.
NTA has not published the 2027 bulletin. In 2026 the pattern was applications from 31 October to 27 November 2025 and Session 1 on 21 to 30 January 2026, with Session 2 on 2 to 9 April. Expect a similar late-October notice on jeemain.nta.nic.in and treat coaching-site dates as guesses until then.
For Paper 1 at Indian centres in 2026: General male ₹1,000 and female ₹800; General-EWS and OBC-NCL male ₹900 and female ₹800; SC, ST, PwBD and third-gender candidates ₹500. Fees are charged per session, and registering for Paper 1 and Paper 2 together costs more.
Yes. The paper is offered in 13 languages, English, Hindi, Assamese, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu and Urdu, chosen at application. Regional languages are tied to centres in the respective states, so the choice can affect where you can sit.
You may sit either or both. NTA counts the best of your two NTA percentile scores, so a second attempt cannot lower your rank. Many students use the January session as a full-scale diagnostic and April as the main attempt, adjusting the plan between the two.
There is no age limit. You must have passed Class 12 in one of the two preceding years or be appearing in the current year, which in practice gives three consecutive years with two sessions each. Institutions may apply their own age criteria at admission, so check the counselling rules.
Yes, one free full-length mock per account, no card. It follows the NTA structure of 75 questions across Physics, Chemistry and Mathematics in three hours with server-controlled timing and +4/−1 marking. You get raw marks and per-section scores; percentiles are not simulated, and the AI tutor explains every answer. See free mock tests →
