For the entrance examination of 2021 there is no notifications released in the official website regarding syllabus. So you should keep an eye on the website for updates.

Secondly in most of the courses , the entrance exam syllabus is generally the BSc syllabus of any standard Indian university. So you can keep your BSc syllabus as the syllabus and start preparing and then sort out when the official syllabus will be released on the website.

I hope my answer helps you. All the very best for your future endeavors!
