Hello,

No in Joint Entrance examination (JEE) main Calculators are not provided. Either physical or virtual calculators are not provided. You need to do all calculations on your own and the questions are formed in such a way that candidates are able to calculate without calculators help. Practice more and more so that you can calculate as quickly as possible which will help you during the exam.
