If NIOS chemistry qualification isn’t valid for DASA, can I supplement it with another recognized exam or course to meet the eligibility criteria for IIITH admissions?

Ans: NIOS Chemistry is unlikely to be accepted for DASA at IIITH

Ans: It is unlikely that IIIT Hyderabad would accept NIOS Chemistry for DASA eligibility because the DASA brochure states that the subjects must be completed outside India. Since NIOS is an Indian board, it does not meet this requirement. However, you could consider taking AP or IB Chemistry to meet the requirements, as these are often recognized as international qualifications. It's best to wait for IIITH's response to your email for official clarification.
Elaboration:
DASA Requirements:
DASA (Direct Admissions for Students Abroad) at IIIT Hyderabad requires applicants to have completed 11th and 12th grades or equivalent outside India, with a minimum of 60% marks in Physics, Chemistry, and Mathematics.
NIOS and IIITH:
While NIOS is a recognized board in India, it's unlikely to be accepted for DASA at IIITH because the DASA brochure specifies that the subjects must be completed outside India.
AP or IB Chemistry:
You could consider taking AP or IB Chemistry through a foreign board to fulfill the requirement for Chemistry. These are often recognized as international qualifications.
Waiting for IIITH's Response:
Since you've already emailed IIITH, it's advisable to wait for their response to your query for official clarification on whether NIOS Chemistry would be accepted.

Ans: For IIITH DASA, Chemistry must be completed and certified outside India as part of your qualifying examination. Taking Chemistry via NIOS (India) will not be accepted. Taking AP or IB Chemistry overseas may be accepted if it results in a recognized certificate. Split mark sheets from different boards are generally not accepted unless the university specifically allows it-wait for IIITH’s official clarification, but plan to get all three subjects on a single, recognized overseas certificate if possible. All The Best.
