B.Arch

Hi, Congratulations on securing 90% in your 12th. NATA score of 130-150 may help in getting admitted to SIR JJ College.

Hi, yes you're eligible for admission in Jamia Millia Islamia. Admission forms will be available soon on the official website. For more details please visit https://www.jmi.ac.in/.

Go for B.Arch in MZU. It is good. The planning department is quite good. Department is new, but still got some good names. Moreover, you won't find many Universities with B.Arch. Only two central universities provide B.Arch here, and here NATA score is better.

The fee structure for all the categories whether general or any other caste is the same. For the exact fee, you can check the official website.

The final AIR will be declared after April 2019 considering the best score out of the two JEE Main attempts for all the applicants, hence based on current percentile we cannot predict whether you will qualify for NITs/SPA or not. Wait for the final AIR declaration
