Birla Institute of Technology and Science Admission Test • Conducted by Birla Institute of Technology and Science (BITS Pilani)
Registration Windows, Slot Booking, Session 1 & Session 2 Schedules, and Historical Patterns
BITSAT's calendar is structured around its distinctive two-session format, and understanding this timeline is essential for candidates deciding whether to target Session 1 only, or to keep Session 2 as a backup for score improvement. Registrations for BITSAT typically open in the last week of December or first week of January and remain open through mid-March, giving candidates close to three months to register, though most serious aspirants complete registration well before the final deadline to secure preferred slot choices.

The registration process is entirely online through the official BITS Admission portal. Once registration closes, BITS Pilani opens a "slot booking" window during which candidates select their preferred test date, shift, and city from the available options on a first-come-first-served basis — meaning candidates who register and book slots earlier get access to a wider choice of dates and cities. This differs from NTA-style exams where city/date allocation is done algorithmically; in BITSAT, slot booking speed directly affects convenience.
| Examination Event | Typical Timing | Key Notes |
|---|---|---|
| Application Form Release | Last week of December | Portal opens at bitsadmission.com |
| Last Date to Apply (Session 1) | Mid-to-late March | Editable window opens briefly after closure |
| Application Correction/Edit Window | 1-2 days after closure | Limited fields editable; photo/signature typically locked |
| Slot Booking Window | 2-3 weeks before exam | First-come-first-served city and date selection |
| Session 1 Exam Dates | Mid-to-late April | Spread across multiple days and shifts |
| Session 1 Score Display | Immediately after test | On-screen raw score shown before leaving center |
| Session 2 Registration (optional) | Late April to early May | For candidates wanting to reattempt |
| Session 2 Exam Dates | Late May to June | Spread across multiple days and shifts |
| Iteration 1 Admission List | Late June to early July | Merit list and campus/branch allotment released |
| Iteration 2 and Subsequent Rounds | July to August | Based on seat vacancies after each iteration |
The roughly four-to-six week gap between Session 1 and Session 2 gives candidates a genuine opportunity for targeted improvement. Candidates who score below their target in Session 1 can analyze their weak sections (using the immediate score breakdown by subject) and spend the following weeks intensively revising those specific areas before Session 2. This is fundamentally different from JEE Main's multi-session model, since in BITSAT only the better of the two attempts counts — there is no averaging or normalization concern across sessions since each session uses a similarly calibrated syllabus and question bank.
Reviewing past years' schedules shows consistent behavior: registration generally opens in the window between late December and mid-January, with the first exam session held in the second half of April through mid-May, and the second session following about four to six weeks later in late May or June. Results and campus admission lists (called "Iterations" by BITS Pilani) are typically released in early-to-mid July, allowing the academic session to begin on schedule in August.
BITS Pilani typically opens a brief correction window of a few days immediately after the main application deadline closes, allowing candidates to fix errors in personal details, contact information, or category/subcategory selection. However, core identity fields such as name, date of birth, and photograph are generally not editable post-submission, so candidates should double-check these carefully during the initial form-filling process.
Registration for BITSAT typically opens in the last week of December or the first week of January on the official bitsadmission.com portal and stays open until mid-March.
Yes, after registration closes, BITS Pilani opens a slot booking window where candidates select their preferred exam date, shift, and city from the available options on a first-come-first-served basis.
Typically four to six weeks separate Session 1 (mid-to-late April/May) and Session 2 (late May/June), giving candidates time to revise weak areas before reattempting.
While application deadlines occasionally see short extensions, once slot booking for a specific date-shift combination fills up, that option is simply removed from selection — there is no guarantee of extension for a specific slot.
The first Iteration list, containing merit-based campus and branch allotments, is typically released in late June or early July, shortly after Session 2 concludes and the combined merit list is finalized.
