To get an accurate estimate of your JEE Main 2026 Session 1 score, follow the guide below:
- Firstly, download your response sheet and the official answer key from the NTA portal.
- After every question, the correct answer is mentioned along with the recorded response, which is the response you made in the exam.
- Match your answers with the correct options given in the answer key. Note down all the correct responses in a sheet along with the number of incorrect responses.
- Here is the reference format to note down the total response count:
- Correct answers
- Incorrect answers
- Unattempted questions
- Apply the formula below to estimate the score:
Estimated Score = (Correct Answers × 4) – (Wrong Answers × 1)
Example Calculation (Reference)
- Correct Answers: 50
- Wrong Answers: 10
Score = (50 × 4) – (10 × 1)
Score = 200 – 10 = 190 Marks
