Utilizing the GATE Answer Key 2026 effectively is key to predicting your scores. The primary objective is to compare your attempted answers with the official correct solutions and compute your estimated marks. This method helps in understanding your performance.
Step 1: Begin by assigning marks for all correctly answered questions.
Step 2: Next, calculate the deductions for incorrect answers. Negative marking applies only to Multiple Choice Questions (MCQs), not to Numerical Answer Type (NAT) questions.
Step 3: Sum up the marks from both 1-mark and 2-mark correct answers.
Step 4: For 1-mark questions, multiply the number of correct answers by 1 and subtract 1/3 of the marks for incorrect attempts.
Step 5: For 2-mark questions, multiply the number of correct attempts by 2 and subtract 2/3 of the marks for wrong answers.
To get your total marks, add the total marks from the 1-mark questions to the total marks from the 2-mark questions, including both MCQ and NAT sections.
