A you are in class 12th right now so the most demanding option nowadays for going in the field of CS is B.Tech in CSE, in India the are different engineering institutions such as NITs/IIITs/IITs/CFTIs/GFTIs which take admission for B.Tech courses on the basis of JEE-Main or JEE-Advance (only for IITs and IIST) score. As you are pursuing class 12th with PCM so you are eligible for appearing in JEE-Main 2021 and if you want admission to NITs/IIITs/CFTIs then you should score a minimum aggregate of 75% in your class 12th if you belongs to General/Unreserved category and 65% if you belongs to any of the reserved category.
