Mera cbse improvement exam mai 75 percent nahi aa raha hai kya mai dubara class 12 Mai admission lai Kai 75 percent laau aur uske baadjee du
Coming to your question, if, for example, you wrote your 12th board exams in 2019 and are planning on taking readmission in 12th standard, you'll write your board exams again in 2020. You'll have a chance to write JEE in 2020 and in 2021,provided you satisfy the required criterias. Hope it's clear to you :)
