JEE Main College Predictor

Shiksha has developed an analytical, algorithmic JEE Main college predictor tool to provide a tentative list of colleges that a student may get based on their rank/percentile. Shiksha’s JEE Main 2026 college predictor uses students' JEE Main percentile or rank, along with the candidate's personal details such as category, gender, and state of eligibility, to predict the data. The data is then analysed against historical cutoffs and trends to provide a list of the most likely colleges for admission. By using this tool, engineering aspirants will be able to prepare a personalised preference list for their JoSAA counselling.
