Hello Yogesh,

Since your board percentage is below 75 percent , so you are not eligible to get admission for B. Arch course through your JEE Mains paper 2 score. However , you are eligible to apply for those colleges where they accept NATA score. Below I have listed some of the colleges in Maharashtra those who accept NATA score - 

• Varati Vidyapeeth College of Architecture 
• Sinhgad College of Architecture 
• Dr D.Y. Patil College of Architecture 
• IES College of Architecture 
• MIT Art Design & Technology University

These are some of the colleges in Maharashtra accepting NATA score. There are total 34 colleges in Maharashtra those who accepts NATA score.
