"Similarly, the fee of general category students has also been doubled. This is a very unfortunate, casteist and anti-poor decision. CBSE should take it back immediately. This is the demand of BSP," she said in another tweet.
The CBSE had recently doubled the fee of Class X and XII Board examinations from Rs 750 to Rs 1,500.
According to the education board, SC/ST students in Delhi will now have to pay Rs 1,200 instead of Rs 50 earlier.
