CET 2026 Negative Marking — 1/3 Rule, Blank OMR Penalty, E-Option and 10% Disqualification Threshold

The Negative Marking Rule Explained

CET 2026 uses negative marking of 1/3 of the question marks for each wrong answer at both Senior Secondary and Graduation levels. Senior Secondary has 120 questions for 240 marks; Graduation has 150 questions for 300 marks. In both papers, each question carries 2 marks, so a wrong answer deducts 0.67 marks.

This is a standard 1/3 system used across RSSB examinations. The net swing between a correct and wrong answer is large: choosing wrong instead of correct creates a 2.67-mark difference (you lose 2 you could have had plus pay 0.67). This asymmetry is what makes attempt selection the main skill tested alongside content knowledge.

The 5-option structure means the probability of a purely random correct answer is only 1 in 5. Eliminating one wrong option makes a random guess among the remaining 4 break-even in pure expected value; eliminating two wrong options makes it positive. Practical risk still matters: skip if you cannot eliminate options with real confidence.

The Blank OMR Circle Rule

Unlike most pen-and-paper exams where leaving a question blank simply earns zero, CET 2026 has a blank-circle deduction rule. If a candidate does not darken any of the 5 circles for a question, the same 1/3 deduction as a wrong answer applies.

This rule catches candidates who skip questions by literally leaving the OMR row empty. The intended skip mechanism is Option E. Darkening E explicitly tells the evaluation system you chose not to attempt the question. No deduction is applied when E is marked.

The blank-circle deduction applies up to 10% of total questions. With 120 Senior Secondary questions, the limit is 12 blank rows; the 13th fully blank row disqualifies. With 150 Graduation questions, the limit is 15 blank rows; the 16th fully blank row disqualifies.

This makes the blank rule two-tier: blanks within the 10% limit attract the standard 1/3 deduction per question, and a blank count above 10% triggers disqualification for the entire attempt.

The E-Option Explained

The E circle in CET 2026 is the not-attempting option. It acts as the official skip marker. When you are certain you do not want to attempt a question, darken E in blue ball-point pen rather than leaving all 5 circles blank.

Darkening E has two practical effects: you pay zero marks for that question (no deduction, no gain), and you keep that question out of the blank-circle count that determines the 10% disqualification threshold.

This means the OMR has a de facto three-outcome system per question: correct answer (+2), wrong answer (-0.67), or E (0). The blank state, meaning none of the 5 circles darkened, is not a valid fourth outcome — it is treated as a penalised wrong answer within the 10% limit, then as disqualification grounds.

Strategy implication: never leave the OMR row for a question completely blank. Either attempt it by darkening one of A, B, C or D, or skip it cleanly by darkening E.

The 10% Disqualification Threshold

The 10% blank-question threshold is the most severe rule in the CET 2026 marking scheme. It makes high blank rates a disqualification risk rather than just a scoring miss.

The calculation is level-specific. CET Senior Secondary: 120 questions x 10% = 12, so the 13th fully blank row disqualifies. CET Graduation: 150 questions x 10% = 15, so the 16th fully blank row disqualifies.

This rule was introduced to prevent candidates from strategically leaving large portions of the paper blank to avoid negative marking. The E-option addresses the same concern legitimately: skip cleanly by marking E, but blanking more than 10% of the paper entirely is grounds for disqualification.

Implication for strategy: do not avoid negative marking by leaving OMR rows blank. Use E generously for any question you are uncertain about, and keep track of your blank count. A safe convention is to never leave any row blank and always mark E when skipping.

OMR Strategy for CET 2026

Build a verified strategy before exam day through mock tests. The most reliable approach for CET 2026 with 5-option negative marking is selective accuracy. Attempt only when confidence is 65% or above, use E for all skips, and never leave rows blank.

Time management differs by level: Senior Secondary gives 2 hours 30 minutes for 120 questions; Graduation gives 3 hours for 150 questions. In both, do a first pass marking E for all uncertain questions, then use remaining time for second-pass review of borderline questions.

After the exam solving time, you get 10 extra minutes to check that all OMR rows have exactly one circle darkened. Use this time systematically: go question by question and confirm one circle per row. Never cross out a circle — an incorrectly darkened circle cannot be changed without a supervisor check.

Mock practice tip: track your wrong answers, E-marked skips, and fully blank rows in separate columns after every mock. The blank row count must stay safely under your level threshold: 12 for Senior Secondary and 15 for Graduation.
