How to Register for IIT JAM Mathematics Without Getting Rejected
To register, create a JOAPS account, upload your Class 10 (SSC) marksheet, photograph and signature, choose papers from different sessions and cities, and pay online.
By Sunil Bansal, Founder · Updated 27 Oct 2026
Key takeaways
- To register, create a JOAPS account, upload your Class 10 (SSC) marksheet, photograph and signature, choose papers from different sessions and cities, and pay online. The official documents page lists no Class 12 or degree marksheet upload.
- Mathematics is a forenoon paper. Valid second papers are Biotechnology, Economics, Mathematical Statistics and Physics; Chemistry and Geology clash.
- Check your photograph and signature against the tables before you submit. A file outside the rules gets a defect notice and can end in rejection if you do not fix it in time.
- The fee depends on your category and on whether you take one or two papers, and a later change costs extra; the fee table below has the amounts.

Most trouble with IIT JAM Mathematics registration starts before the form is opened. According to the JAM 2027 Information Brochure, the exam is a computer-based test held in around 114 cities, with around 3,000 seats at 23 IITs on offer. A wrong paper pair, a blurred photograph or a missing certificate costs you time, and sometimes money, at the busiest point of the cycle.
JAM 2027 has seven test papers on a single day, and Mathematics shares its session with Chemistry and Geology. Pick one of those as your second paper and the combination is not allowed.
Every rule on this page comes from the official JAM 2027 website or its Information Brochure, with the source beside it. The form is filed on JOAPS, the JAM Online Application Processing System, for JAM 2027, which Indian Institute of Technology (IIT) Kharagpur organises.
Check the deadline box first. The last date has been extended more than once, and the portal, not this page, has the final word.
Where do you confirm the IIT JAM Mathematics registration deadline?
Confirm it on the JAM 2027 homepage. As of 27 October 2026 it shows 24 October 2026 as the last date to apply, marked extended.
| Source | Date it gives | Note |
|---|---|---|
JAM 2027 homepage (official) | 22 October 2026 | Labelled “Last date to apply (extended)” |
| 19 October 2026 | Printed in the brochure, which says it is correct as on 22 August 2026 (§5.1) | |
| Some third-party guides | 12, 19, 22 or 24 October 2026 | Each reflects a different stage of the extensions; follow the homepage text |
Still open? If the homepage shows a last date that has not passed, apply on JOAPS and pay before it.
Closed? If the last date has passed and the homepage shows no newer one, the application window is closed. Go to the sections on defects, corrections and the admit card.
Extended again? Follow the homepage; the brochure PDF may keep the older date, as it does today.
Which papers can you pair with Mathematics under the IIT JAM two papers rule?
Mathematics (MA) is a forenoon paper, so a second paper must come from the afternoon session: Biotechnology, Economics, Mathematical Statistics or Physics.
What is the forenoon and afternoon rule?
A candidate can sit one or two test papers, and two only if they are scheduled in different sessions, per the JAM 2027 test schedule and brochure §2.2, p.15. The forenoon session runs 9:30 am to 12:30 pm and the afternoon session 2:30 pm to 5:30 pm, both on Sunday 14 February 2027.
Which papers are valid pairs with Mathematics?
| Paper | Code | Session | Pair with Mathematics |
|---|---|---|---|
| Mathematics | MA | Forenoon | Your first paper |
| Chemistry | CY | Forenoon | Clash |
| Geology | GG | Forenoon | Clash |
| Biotechnology | BT | Afternoon | Valid |
| Economics | EN | Afternoon | Valid |
| Mathematical Statistics | MS | Afternoon | Valid |
| Physics | PH | Afternoon | Valid |

Does paper choice replace the eligibility check?
No. Choosing a second paper does not replace the check of your degree and subjects against each admitting IIT’s minimum educational qualifications, which IIT JAM Mathematics eligibility covers. JAM 2027 itself sets no minimum percentage (JAM FAQ).
How do you register for JAM Mathematics on JOAPS, step by step?
To register for IIT JAM Mathematics, create a JOAPS account through jam.iitkgp.ac.in, fill in the form, choose papers and cities, upload documents, then pay online.
- Open JOAPS
Go from the JAM 2027 homepage to joaps.iitkgp.ac.in.
- Create your account
Register with your name, a valid email address, an active mobile number and a password. JOAPS sends an Enrollment ID and a one-time password (OTP) to your email and mobile; you use the Enrollment ID with your password to submit the application (brochure §3.1, p.23).
- Fill in your details
You can save a partly filled form and resume later (brochure §3.3, p.25).
- Choose papers and cities
Give a first, second and third exam city; your first city fixes the zone (brochure §3.2, p.24).
- Upload and enter documents
Upload your Class 10 marksheet, photograph and signature. Enter one photo ID: Aadhaar, driving licence, PAN, passport or voter ID (brochure §3.3, pp.25 to 26).
- Review and pay
Click Save and View, check every field and document, fix any mistake, then click Proceed for Payment (brochure §3.7, p.32). Once the form PDF is generated, the official FAQ says you cannot edit the data, so review before you pay.
- Confirm the payment
Wait for the confirmation on JOAPS. If you are unsure whether it went through, log in after about an hour, and start a new payment only if it is not shown (brochure §3.7, pp.32 to 33). Refund timing is in the FAQ below.
Which IIT JAM documents are required, and what are the photo and signature size rules?
The official documents page makes one certificate mandatory: the X Standard (SSC) marksheet or certificate (documents page).
| Document | Applies to | Official rule |
|---|---|---|
| Class 10 (SSC) marksheet or certificate | Everyone | Required; scanned copy showing date of birth (documents page, brochure §3.3) |
| Class 12 and degree marksheets | Not an upload | Not on the official documents page; degree details are entered in the form (brochure §3.3, p.25). Some third-party guides list them as uploads |
| OBC-NCL or EWS certificate | If you belong to either | Annexure VI (OBC-NCL) or Annexure VII (EWS) format, issued on or after 1 April 2026 (brochure §3.6, p.31). Some third-party guides omit the issue-date rule |
| SC or ST certificate | If applicable | Valid certificate from authorised officials (brochure §3.6, p.31) |
| PwD certificate and UDID number | If applicable | Certificate plus UDID number (brochure §3.3, p.25). Some third-party guides omit the UDID number |
What is the IIT JAM photo size and format?
The documents page and the brochure give slightly different file-size ranges, so the table shows both and the overlap. If the portal shows different limits when you upload, follow the portal.
| Rule | Value | Source |
|---|---|---|
| Format | JPEG/JPG | |
| Print size | 3.5 cm width × 4.5 cm height | |
| Pixels | 240×320 minimum, 480×640 maximum | |
| File size | 50 to 200 kB | |
| File size | 20 to 200 kB | |
| Safe overlap | 50 to 200 kB | Inside both ranges above |
| Aspect ratio (width : height) | 0.66 to 0.89 | |
| Colour and background | Recent, colour, white or very light background | |
| Face | At least 50% of the area, full face looking at the camera; forehead, eyes, nose and chin clearly visible | |
| Glasses | Clear glasses only; no dark or tinted lenses | |
| Phone photos | Poor-resolution phone photographs and self-composed portraits may lead to rejection |
What is the IIT JAM signature size and ink rule?
The documents page and the brochure also differ on the signature file size, so the table shows both and the overlap.
| Rule | Value | Source |
|---|---|---|
| Format | JPEG/JPG only | |
| Box size | 2 cm height × 7 cm width | |
| Pixels | 80×280 minimum, 160×560 maximum | |
| File size | 50 to 150 kB | |
| File size | 10 to 150 kB | |
| Safe overlap | 50 to 150 kB | Inside both ranges above |
| Aspect ratio (width : height) | 3.15 to 4.04 | |
| Ink | Black or dark blue | |
| Not accepted | Capital letters, initials, any other ink colour | |
| Capture | Use a scanner |
Pro Tip: Sign with a black or dark blue pen inside a 2 cm × 7 cm box on white paper, scan it on a scanner, and crop the image to the box border, as the documents page asks.
What do category and PwD certificates need?
OBC-NCL and EWS certificates must be in the prescribed format and issued on or after 1 April 2026, by authorised officials. SC and ST certificates are uploaded too, and a PwD certificate goes with your UDID number (documents page, brochure §3.6, p.31).
| Rule | Value | Source |
|---|---|---|
| Certificate file format | ||
| Certificate file size | 10 to 300 kB |
The brochure says you must submit the same certificate again during admissions to the admitting institutes (p.31).
The brochure says an application without the required valid documents is liable to be rejected, and it does not say what category you are placed in if the OBC-NCL or EWS certificate is missing (brochure §3.6, p.31). [Confirm with client: category outcome for a missing OBC-NCL or EWS certificate.]
What is the IIT JAM application fee, and what does a correction cost?
As of October 2026, the fee depends on your category and on one or two papers, as the table shows (application fee page, brochure Table 2.2, p.15).
| Category | One paper | Two papers |
|---|---|---|
| Female / SC / ST / PwD | ₹1,000 | ₹1,350 |
| All others | ₹2,000 | ₹2,700 |
The fee is neither refundable nor transferable, and a submitted application cannot be cancelled. JAM charges no processing fee, but bank or gateway charges are yours to bear (application fee page).
Changing exam city, test paper, category, gender or date of birth costs ₹300 plus the applicable difference in application fee (application fee page).
Our worked example, assuming the difference means the gap between the two-paper and one-paper fee: adding a second paper adds ₹350 (₹1,350 minus ₹1,000) for Female, SC, ST and PwD candidates, or ₹700 (₹2,700 minus ₹2,000) for all others. With the ₹300, that is ₹650 or ₹1,000 in total.
Which mistakes get a JAM application flagged or rejected?
The JAM FAQ names a signature outside the specification as a ground for a defect notice, and the brochure warns that poor-quality photographs lead to rejection (p.27).
- Paper pair. Pass: different sessions.
- Class 10 scan. Pass: uploaded, legible; a missing one makes the application liable to be rejected (brochure p.31).
- Photograph. Pass: meets the photograph table.
- Signature. Pass: meets the signature table.
- OBC-NCL or EWS certificate. Pass: valid certificate in the Annexure format, issued on or after 1 April 2026 (see the category section).
- Photo ID. Pass: a listed ID, original carried on exam day.
- Payment. Pass: JOAPS shows fee confirmation.
- Defect alerts. Pass: you check email, SMS and JOAPS status and fix defects in time.
What can the IIT JAM correction window change, and what can't it?
As of 21 October 2026, the official sources name five fields you can change after submitting, for a fee: exam city, test paper, category, gender and date of birth (application fee page, brochure p.16). The cost is in the fees section.
The brochure says paper changes must be made before 10 November 2026. Treat the window's dates as tentative until the portal shows them.
Scrutiny continues after the portal closes (JAM FAQ), and you are told of defects by email or SMS.
What should you do after you submit the form?
As of 21 October 2026, the brochure gives 5 January 2027 as the admit card release date, running until the exam on 14 February 2027 (brochure §3.9, p.34); the portal confirms the actual date.
The admit card is not sent by post or email. Print it, preferably in colour, and carry the original valid photo ID you gave at registration. Report a discrepancy to jam@iitkgp.ac.in (brochure p.34).
