Dear Harsh, the eligibility criteria for getting into SPA, Delhi is that you should have passed your 10+2 with Mathematics as a compulsory subject with an aggregate of 50%. And the selection is based on your performance in JEE Mains examination. So, it doesn't categorize your State Board as ineligible to apply. If you can score pretty good in JEE Mains, you have every chance of getting into this Institution. Hope this helps!
