JoSAA 2026 – Can I Update Choices After Mock Allotment?

JoSAA typically releases 2 mock allotments before Round 1 choice locking. Mock 1 is released early in the choice filling window, Mock 2 is released a day or two before the final lock deadline. Both are simulations — you can edit choices after each mock result before the final lock deadline.

No — mock allotments are simulations based on choices submitted by candidates up to that point in time. Final Round 1 allotment uses the full set of locked choices from all registered candidates, which changes significantly as more students register and lock choices. Treat mock results as directional guidance, not a guarantee.

If your mock result shows 'Not Allotted': add more choices in the rank range close to and slightly above your expected allotment, plus add safety net choices well below. If allotted something you do not want: reorder your choice list so preferences are correctly ranked. If happy with mock result: ensure you have added enough choices above it for upgrade attempts via Float.

Yes — during the choice editing window (after mock allotment and before final lock), you can add new college-branch combinations, remove existing ones, and completely reorder your list. The mock allotment was just a snapshot; the final lock is what counts.

If you make edits but do not re-lock before the lock deadline, different portals handle this differently — some may auto-submit your last saved choices, others may use your pre-edit version. Do NOT rely on auto-save. Always explicitly lock/submit your final choice list before the deadline. Treat the lock action as mandatory.
