RRB JE EC Mock Tests: Free Online Practice

Online mock tests for RRB JE EC in the CBT format, built around the Electronics and Communication paper.

Mock tests are the closest practice you get to the RRB JE computer-based test. For Electronics and Communication candidates, they matter twice: CBT 1 needs speed in maths and reasoning, and CBT 2 needs accuracy across 100 technical questions with one-third negative marking.

Types of Mock Tests

Test type

What it covers

When to take it

Topic-wise test

One technical topic, such as digital electronics or modulation

Right after finishing the topic

Sectional test

One CBT 1 section or the common CBT 2 sections

Weekly, from the middle of your plan

CBT 1 full-length

100 questions in 90 minutes

Twice a week near the exam

CBT 2 full-length

150 questions in 120 minutes with the 100-mark technical section

Weekly in the last phase

Practise in the Current Pattern

CBT 1 has Mathematics (30), Reasoning (25), General Awareness (15) and General Science (30). CBT 2 has General Awareness (15), Physics and Chemistry (15), Computers (10), Environment (10) and Technical Abilities (100). A wrong answer costs one-third of a mark in both. Set your mocks to the same limits.

How to Use Mock Tests

  1. Start with topics: test each technical subject soon after you study it so gaps show early.

  2. Add sectional tests: practise 20-minute sets on the common sections to build speed.

  3. Move to full-length papers: take them at the real exam time of day and attempt the whole paper in one sitting.

  4. Analyse the same day: a mock without review adds little.

How to Analyse a Mock

  • Wrong answers: note whether the cause was a concept gap, a formula slip or a guess.

  • Slow questions: mark those that took over two minutes and find shorter methods.

  • Skipped but solvable: these are the cheapest marks to win back.

Common Mistakes

  • Taking only full-length tests and skipping topic practice.

  • Guessing heavily without eliminating options.

  • Ignoring the common CBT 2 sections because they feel easy.
