hey,

sorry to say but if you have not cleared your mathematics subject in boards examination then you are not eligible for the same as the basic eligibility criteria for the admission in B.tech course is candidate must have passed their 10+2 this year from any recognized board with atleast 5 subjects and out of which not more than 2 subjects should be vernacular subjects and candidate must have secured a minimum aggregate of 45 percent marks in physics, chemistry and mathematics altogether and with minimum 30 percent aggregate marks in english

hope this helps !
