BTSC JE Exam Pattern

The test is a computer-based, objective paper of 100 questions in Hindi and English, with a duration of 2 hours. Each correct answer gets 1 mark and each wrong answer costs 0.25 marks. It may be held in more than one shift, with normalisation. Questions are based on the AICTE 3-year diploma civil engineering curriculum. Minimum qualifying marks are 40% for General, 36.5% for BC, 34% for EBC, and 32% for SC, ST, women and persons with disabilities.

Selection: the merit list combines 75 marks from the written test (your score scaled to 75) and up to 25 marks for experience as a contract JE, at 5 marks per completed year, counted up to 12 December 2025. Experience needs a salary payment certificate in the format given in the advertisement. After the test, shortlisted candidates are called for document verification and departments are allotted by option and merit.
