Hi aspirant,

Sir JJ College of Architecture is one of the top institute in India and has limited seats of around 70. Hence, it has a very high cutoff. For admission into JJ College you need have an aggregate of atleast 150. The aggregate is calculated by adding 50 % of your NATA score and your board pecentage. 

Given your marks your aggregate is around 144, which is a good score, but because of the limited seats available your chances of getting admission are low. However, this is just a prediction and the cut-offs are likely to change every year. So don't lose hope. All the best!
