What is OMR?

The CLAT OMR (Optical Mark Recognition) sheet is the physical answer sheet used in the offline CLAT exam. Candidates mark answers by fully shading one bubble (A, B, C, or D) per question using a black or blue ballpoint pen. A scanner reads the marks, so accuracy in shading directly affects your score.

Is CLAT still an OMR-based offline exam?

Yes. As per the Consortium of National Law Universities, CLAT continues to be conducted in offline, pen-and-paper (OMR) mode. The exam has 120 questions in 2 hours, with +1 for a correct answer and −0.25 for a wrong answer. There is no computer-based (CBT) mode for CLAT as of now.

Importance of Correctly Filling CLAT OMR Sheet

As important as knowing the correct answers is filling the CLAT OMR Sheet correctly. Here's why:

  • Avoid Marking Errors: If you don't fill the OMR sheet appropriately, your answers might not be read correctly, leading to unnecessary negative marking.
  • Ensures accuracy in evaluation Since the CLAT OMR Sheet is scanned by a machine, clarity and accuracy in marking are prerequisites, as any over-shading can be confusing to the scanner.
  • Prevents disqualification: Answers that are incorrectly marked, for example, doubly marked answers, invalidate the answers.
  • Saves Time: Properly marking the CLAT OMR Sheet in a structured way ensures you do not waste your time correcting mistakes during the exam.

  • Use a Black or Blue Ball ballpoint pen: Stick to these colour options. Gel pens, fountain pens or pencils are a strict no-no.
  • Fill the Circles: When marking your answer, ensure that the entire circle is filled. The OMR machine might not detect partially shaded options.
  • Do Not Overlap: If you feel you've marked an answer wrong, don't overwrite or mark another option in the same row. It will be considered void. Instead, carefully erase the initial mark (if allowed) and then darken the correct circle.
  • Be Gentle: Pressing too hard might damage the CLAT OMR sheet. On the other hand, being too light might not reflect the mark. So, it's a balance you need to strike.
  • Avoid Stray Marks: Be very careful not to make any unnecessary marks on the sheet, as the machine might misinterpret them.
  • Fill in the Details Carefully: At the top of the sheet, there are usually sections where you can fill in your name, roll number, and other personal details. Make sure these are filled in accurately, as errors can prevent your sheet from being evaluated.
  • Work Fast but Thoughtfully: OMR sheets can be time-consuming, so ensure you're marking them alongside answering questions to avoid a last-minute rush.
