Earlier, the fees to sit for an exam for an additional subject was ₹150 for general, and non-existent for SC/STs. Both will now have to fish out ₹300 for additional subjects.

The All India Parents Association (AIPA) has strongly opposed the decision by CBSE. Advocate and President of AIPA, Ashok Aggarwal said that the decision will be challenged in court. He further added

This major hike in fees is unconstitutional and totally against the right to education of students. This fee hike will be challenged in court. The CBSE is discharging public functions and is governed by Article 14 of the Constitution and therefore bound to act proactive towards educational needs of children of masses.
