JKSSB SI Telecom Free Mock Test + 10 MCQs

JKSSB Sub-Inspector (Telecommunication) is a different exam from every other JKSSB post. Alongside the usual numeracy, reasoning, English and J&K GK, it has a real engineering part, and that is where a free mock test routine should spend most of its time.

How to split your preparation

• Part B first: signals and systems, analog and digital electronics, microprocessors, communication systems, networking, databases and cybersecurity
• Part A in the gaps: numeracy, reasoning, English and J&K GK are quick to revise and easy to keep fresh
• Every week: one mixed test across both parts, then review which part cost you marks

What to practise first

• Electronics & communication: engineering mathematics, devices and circuits, digital electronics, microprocessors and communication systems
• Computer science & IT: networking and the OSI model, programming basics, databases, cybersecurity and IT systems
• Part A: basic numeracy, series and coding, comprehension and J&K GK. Read the SI Telecom syllabus guide

A note on this exam's question bank

Our Part A subjects have deep question banks. Part B now has about 1,300 technical questions across 10 subjects: electronics, mathematics, communications and networking are the deepest (200+ each), while databases, cybersecurity, IT systems, IoT and AI are smaller (45 to 85 each) and still growing. Keep a standard textbook for each subject next to our practice.
