JEE MAIN 2018 Expected Cut off

Cut off marks are the minimum marks scored by the candidate in order to clear the entrance examination. Students having marks less than the cut off marks are not eligible to get admission in the desired course. As per the difficulty level of the examination, cut off marks keep on changing every year.

Several factors would contribute to determining cutoff. Some of prominent factors are indicated below:

  • The difficulty level of the exam
  • Availability of seats
  • Total number of students appearing for the exam
  • Previous year cut off trends
  • Reservation Norms

The Cutoff for last 3 years will give you better insight into the expected minimum score required in JEE Main 2018. Last year’s cutoff saw a major dip after the decision to scrap class XII score for calculating JEE Main All India Ranks.
