Common questions
Online prep FAQ
Is this a live Bihar Police coaching batch?
No. KarmSakha provides a self-paced foundation workbook, digital notes, original-model practice and review tools. There are no live classes or fixed batch timings.
Does it cover Prohibition Constable and Jail Warder?
The 03/2025 written syllabus uses the same Class IX–X subject framework, so the academic modules overlap. Eligibility, quota, PET and merit rules are presented separately for each post.
Can I try a test before paying?
Yes. Start with the free 25-question diagnostic. The 100-question original model is a timed paid practice test; neither test is represented as a previous-year paper.
