No, an NWAC (National Wisdom & Accreditation Council) Class 12 certificate is not valid for B.Tech admission in BITS Pilani.

BITS Pilani requires candidates to appear for their own entrance exam, BITSAT (Birla Institute of Technology and Science Admission Test), for B.Tech admissions.
BITS Pilani typically accepts Class 12 certificates from recognized national boards like CBSE or ISCE, or state boards affiliated with these national boards.

NWAC is not a recognized national board for Class 12 education in India. Universities like BITS Pilani rely on established boards with standardized curriculum and evaluation processes.
