JoSAA Examination Guide

"Applying" for JoSAA means registering on josaa.nic.in and building your ranked choice list — there is no separate exam application, since your JEE Main and/or JEE Advanced rank already determines your eligibility.

Step-by-Step Registration Process

• Step 1 - Confirm Eligibility: Ensure you hold a valid JEE Main rank (for NIT+ eligibility) and/or JEE Advanced rank (for IIT eligibility), along with meeting the Class 12 academic eligibility criteria.

• Step 2 - Register on JoSAA Portal: Create your JoSAA login using your JEE application number and other verification details.

• Step 3 - Fill Personal and Academic Details: Confirm personal information, category, PwD status (if applicable), and Class 12 details exactly as per your JEE records.

• Step 4 - Study the Seat Matrix: Review the published seat matrix across all eligible institutes and branches before building your choice list.

• Step 5 - Fill and Save Choices: Build your ranked institute-branch preference list, revising as needed across the two mock allotment cycles.

• Step 6 - Lock Choices: Lock your final choice list before the deadline; no further edits are possible after locking.

• Step 7 - Respond to Each Round: After each round's allotment, choose freeze/float/slide/withdraw and complete the required fee payment and document upload within the response window.

Fee Structure

The Seat Acceptance Fee is paid at the time of accepting an allotted seat in any round, not at initial registration, and is later adjusted against the institute's total tuition fee. Exact amounts should always be confirmed against the current year's official JoSAA business rules document.

Documents Required

JEE Main and/or JEE Advanced scorecard/rank card; Class 10 and Class 12 mark sheets and certificates; category certificate (if applicable, issued within the validity period specified); PwD certificate (if applicable); a valid photo ID; and passport-size photographs.

Choice Filling Window and Revision

Candidates can revise their choice list freely during the initial filling period and after each mock allotment, right up until the final locking deadline — there is no limit on the number of revisions during this window, encouraging careful, iterative refinement of the preference order.

Common Registration Mistakes to Avoid

,

Entering category or personal details that do not exactly match JEE Main/Advanced records; filling too short a choice list and risking no allotment at all; failing to revise choices after reviewing mock allotment results; and missing the final choice-locking deadline due to last-minute indecision.

,

Help Desk and Grievance Channels

,

JoSAA maintains a dedicated helpdesk and grievance redressal mechanism accessible through the official portal for issues related to registration errors, payment failures, or seat allotment discrepancies — candidates should raise any concern promptly given the tight round-to-round timelines.

Registering With Guardian Assistance

,

Given the financial commitment and document complexity involved, many candidates complete registration and fee payment with a parent or guardian present, ensuring accuracy across all the detailed personal, academic, and category information required.

,

What Happens After Submission

,

Once registration and initial choice-filling are complete, candidates receive confirmation via email/SMS. This becomes the reference point for all subsequent steps — mock allotments, round-wise results, and final reporting — so candidates should store their login credentials securely throughout the six-to-seven-week process.

Also verify your bank's per-transaction online payment limit before attempting the Seat Acceptance Fee payment, since amounts in the ₹17,500-₹35,000 range can exceed default limits on some cards.

Keep your registered email and mobile number active throughout the process, since round-by-round notifications, payment reminders, and reporting instructions are communicated primarily through these channels with short response windows.

Double-checking every entered detail against your original JEE application before final submission remains the single best safeguard against avoidable registration errors.
