The provisional answer key released this morning at 10:00 IST starts a tight, high-stakes seven-day countdown. By Tuesday, 2 June 2026 (17:00 IST), JoSAA 2026 registration tentatively opens — and what you do between today and then will quietly decide whether you walk into the right IIT branch or stumble into a sub-optimal choice list out of panic. This is the day-by-day roadmap from provisional answer key (25 May) to JoSAA registration (2 June), built around the official calendar published on jeeadv.ac.in.
The 7-day calendar at a glance
| Day | Date | Headline task |
|---|---|---|
| Day 1 | Mon, 25 May | Download provisional key, calculate raw score, identify defensible objections |
| Day 2 | Tue, 26 May | File objections before 17:00 IST — with citations only |
| Day 3 | Wed, 27 May | Build category-aware shortlist of 25–40 IIT programs of genuine interest |
| Day 4 | Thu, 28 May | Pull last 3 years’ opening/closing ranks; widen list to 80–120 options |
| Day 5 | Fri, 29 May | Decide on home-state quota strategy and gender-neutral vs female pool |
| Day 6 | Sat, 30 May | Stress-test your draft order with a parent / mentor / senior |
| Day 7 | Sun, 31 May | Quiet day — revisit and lock document checklist for JoSAA upload |
| Result | Mon, 1 June (10:00 IST) | Result + final answer key — reorder list against actual CRL |
| Registration | Tue, 2 June (17:00 IST) | JoSAA registration opens at josaa.nic.in |
Day 1 (today) — score self-calculation, not score prediction
Today the goal is a defensible aggregate, not a wishful one. Open the provisional key alongside your response sheet, log each question into a spreadsheet, and apply the official marking scheme: +3/−1 for single-correct, +4 with partial credit and −2 for multiple-correct, +4/0 for integer. Record both aggregate and subject-wise raw — JEE Advanced enforces a per-subject cut-off, not just an aggregate one. Full marking-scheme breakdown in our 31-Hour Objection Window Playbook.
Day 2 (26 May) — objections, but only with citations
The objection window closes at 17:00 IST tomorrow. File only challenges you can defend from NCERT, H.C. Verma, Irodov, J.D. Lee, Cengage or another standard reference. Save a screenshot of every citation. If an objection is accepted on 1 June, the correction applies to every candidate — making thoughtful, well-cited challenges genuinely high-leverage.
Day 3 (27 May) — build the “genuine interest” shortlist
Before you look at any rank cut-off, write down 25–40 program-institute combinations you would actually be happy to study. Use the official JoSAA seat matrix page once published; until then, use the 2025 seat matrix as a proxy. Filter on:
- Branch fit: do you actually want this 4-year curriculum, or just the brand?
- Location reality: can your family support the institute geographically?
- Programme length: are you open to 5-year Dual-Degree / Integrated M.Tech?
Day 4 (28 May) — pull official OR-CR data and widen to 80–120
Open josaa.nic.in/or-cr and pull last three years’ opening & closing ranks for every program in your shortlist. Now expand the list:
- Programs whose closing rank is 30–40% above your expected CRL — reach options at the top.
- Programs comfortably within your CRL band — target options in the middle.
- Programs well within your CRL — safe options at the bottom, so the locked seat is one you can live with.
Counselling experts call this the reach-target-safe pyramid; JoSAA permits up to ~250 choices, but a curated 80–120 outperforms a panicked 200+. Detailed strategy in our JoSAA Choice Filling Strategy.
Day 5 (29 May) — home-state quota & female-supernumerary pool
If you are applying to NITs/IIITs/GFTIs alongside IITs, the home-state vs other-state quota often doubles your effective seat pool inside your domicile state. For IITs, the female pool (supernumerary seats introduced to raise women’s participation) means female candidates effectively see two parallel cut-offs — gender-neutral and female-only. Mark both columns when pulling OR-CR data on Day 4. The official seat matrix page publishes both pools transparently.
Day 6 (30 May) — stress-test with a second pair of eyes
Print your draft choice list. Walk a parent, a mentor, or an alumnus through your top-20 entries. Three questions to answer out loud for each:
- Why is this higher than the one below it?
- If JoSAA freezes me at this seat, do I still feel good?
- Have I confused brand with branch?
Re-order based on this conversation, not on coaching-institute rumour lists.
Day 7 (31 May) — document & mindset prep
JoSAA registration on 2 June will require scanned uploads. Pre-stage:
- Class 10 certificate (date of birth proof)
- Class 12 marksheet (or admit card if result pending)
- Category certificate (SC/ST/OBC-NCL/EWS) issued in the correct format and validity
- PwD certificate (if applicable)
- Recent passport-size photograph and signature
All scans should be PDF/JPEG within JoSAA’s size limits (check the 2026 Business Rules when published — archived at josaa.nic.in/information-bulletin).
Result day (1 June) — reorder, do not panic-redo
Your CRL on 1 June will either confirm or shift your Day 4 estimate. If your actual rank is within +/− 1 500 of your assumed band, your shortlist holds — just reorder. Only rebuild from scratch if your CRL lands in a completely different bracket. Cross-reference against our IIT Seat Matrix 2026 Reading Guide.
Registration day (2 June) — what actually happens at 17:00 IST
JoSAA opens registration at josaa.nic.in on Tuesday, 2 June at 17:00 IST (tentative, per the JEE Advanced 2026 official date sheet). You will log in with your JEE Main 2026 application number and password. Note: JEE Advanced credentials are not directly used; JoSAA uses your JEE Main login.
Once in, you confirm personal details, then enter the choice-filling module — where the list you spent Days 3–7 building now goes in, in your preferred order. JoSAA does not save partial choices forever; lock and freeze after every editing session.
FAQ
Why is there a 7-day gap between the answer key and JoSAA?
The gap allows IIT subject panels to process objections (closing 26 May), publish the final key and result on 1 June, and hand normalised data to JoSAA for 2 June onwards — per the official JEE Advanced 2026 calendar.
Will JoSAA dates definitely be 2 June?
The JEE Advanced 2026 important dates page lists JoSAA process commencement as tentative on 2 June at 17:00 IST. Confirm the final date on josaa.nic.in closer to result day.
How many choices should I fill?
JoSAA allows up to ~250 choices but a focused 80–120 reach-target-safe list typically outperforms exhaustive lists, because every choice must be one you would accept.
Do I need to pay anything for JoSAA registration?
Initial registration is free; a partial seat-acceptance fee is charged later if you are allotted a seat (refunded against final admission). Full fee schedule in JoSAA Business Rules when 2026 version is released.
What if AAT is in my plan?
AAT is on Thursday, 4 June (09:00–12:00 IST) at jeeadv.ac.in — relevant only for B.Arch at IIT Kharagpur and IIT Roorkee. AAT result is on 7 June.
