Central Board Of Secondary Education [CBSE] — Revised syllabus of class X 2020-21 boards

With due respect I'd like to say that the datesheet released before was completely fine for students with 5 subjects but seemed a problem for students appearing for jee main and other exams too therefore it has been revised, says the help box but if it was so then why wasn't that made a point of importance before? We'd booked our tickets accordingly and now we've exam on those dates and we can't cancel tickets too since we're 40 people in number. Please don't keep math paper on 2nd June, either make it a day after or on the previous told dates only. Please.
