The TANCET cutoff for University Departments of Anna University for SC category students is somewhere near 51. So it would be a little difficult for you to get into the college. But you can definitely look out for other colleges you can get with your rank like 

• St. Joseph's college of Engineering 
• Easwari Engineering college 
• RMK Engineering college 
• Sona School of Management 
• PSG Institute of Management 
• Galaxy Institute of Management and other private colleges. 

Good luck
