Hey Akash In response to your question that if you score 120 in UPTU exam then I would like to tell you that the total marks awarded in UPTU exam are 600 and the minimum qualification needed for general category is 25% which comes out to be 150 marks and for reserved category British 20%  which comes out to be 120 marks so if you score 120 marks then either you are not qualified that means you are not eligible to take college through your UPTU score or you are just qualified in which case you won't get computer science stream in any of the colleges as it is the top most looked after stream.
