Justice K R Mohapatra allowed only seven days to the CBSE to complete the process of re-evaluation and supply of photocopies of answer sheets.
Some class XII students, whose results were published in May, had alleged discrepancies in the marks awarded to them and were seeking fresh evaluation of their answer papers.
The high court initially had allowed 22 students to apply for re-evaluation, of which only 18 students applied for reevaluation of 51 papers.
While the CBSE had failed to meet the deadline fixed by the high court, it had preferred a time petition seeking at least 15 more days to complete the process.
A single-judge bench of Justice K R Mohapatra, however, allowed only seven days to the CBSE to complete the process.
