TCS iON exam interface: how the CBT screen works
Most bank, SSC and railway exams are computer-based tests on a TCS-style screen. Knowing the buttons and colours before exam day saves minutes and avoids costly mistakes.
The question palette: 5 colours you must know
Buttons on the screen
Save & Next
Saves your selected option and opens the next question. If you pick an option and click a palette number instead, your answer may not be saved.
Mark for Review & Next
Flags the question so you can return to it. If you also selected an option, the question becomes “Answered & Marked for Review”.
Clear Response
Removes the option you selected. Use it to leave a question unattempted and avoid negative marks.
Submit
Ends the test. In exams with sectional timers, each section submits automatically when its clock reaches zero.
Common mistakes on exam day
- Selecting an option and jumping with the palette, so the answer is never saved.
- Forgetting that a question marked for review with an option selected is usually evaluated.
- Watching the overall clock in a sectional-timer exam and losing a section to the countdown.
- Scrolling a long Data Interpretation table on a small exam-centre monitor for the first time.
The fix for all of them is the same: take your mocks in the same interface you will see in the hall. Every CBTMock test uses it.
