3. Avoid Guesswork, Negative Marking is Applicable

There shall be negative marking in the CDS 2023 exam wherein if a candidate marks a wrong answer, a penalty of 0.33 marks will be deducted. There shall be a negative marking when a candidate marks more than one answer even if one of the selected options is correct. However, it is best to leave a question blank if not sure of the answer. There shall be no penalty if a question is left blank.
