Academy & Exam OS by OsDot Solutions is self-hosted mock test and online exam software for coaching institutes. Your institute runs its own website, question bank and server-timed Mock Tests on its own installation.
Build the bank with Single Choice MCQ, Multiple Correct MCQ, Numerical and Written questions and shared passages, with LaTeX and mhchem notation. Import questions from CSV with a preview, row errors and a duplicate policy. Assemble sectioned Mock Tests from fixed or random-draw question pools, with up to 200 questions per Mock Test. Marking is set per section: the institute default is +4 / −1 / 0, and you can change it. Publishing a test creates an edition that freezes its questions and marks.
On exam day, deadlines are kept on the server and answers are autosaved. Afterwards you choose when results are released, mark written answers, regrade, and show a leaderboard on the web.
Every edition includes the PHP web application, the Flutter source of the student app and the documentation. Buy & Own: Single Site for $67 or Multi Site for $127, a one-time price with a perpetual usage licence. Hosted Plan: $12 a month or $120 a year, installed, hosted and updated by OsDot. Setup: Free — launch offer.

Mock Tests with up to 200 questions per attempt. A test can have sections, each drawing from a fixed or random-draw question pool, with its own marking. Tests start as working drafts; when you publish one, an edition is created that freezes its questions and marks.
