What is an OMR Sheet?

An OMR (Optical Mark Recognition) Sheet is a specially designed answer sheet used by MEC to evaluate entrance examinations through computer scanning technology.

The scanner reads dark-filled bubbles and automatically calculates your score. Therefore, proper filling of bubbles is extremely important.

🔢 Step 2: Fill Your Roll Number Correctly

One of the most important sections of the OMR sheet is the Roll Number area.

Candidates must:

Example

If your Roll Number is:

12345678

Then fill the bubbles corresponding to:

1 → 2 → 3 → 4 → 5 → 6 → 7 → 8

Warning: A wrongly filled roll number can result in difficulties identifying your answer sheet.
