Hi Ammu,

Since you haven't mentioned your category, I am assuming it to be General category. Based on this and your rank,  you might not be able to get a seat in CBIT for MBA as their expected cutoff is around 600 rank. However you might get a seat in CBIT for MCA. Other colleges you may get are:

• Sri Krishnadevaraya University Anantapur
• Sri Vidyaniketan Institute of Management
• Andhra Loyola Institute of Engineering And Tech
• Vignans Institute of Information Technology
• CMR College of Engineering & Technology
• Krishna University
• Vidya Jyothi Inst Of Tech
• Vardhaman College of Engineering
• Vishwaviswani Institute of Syst. & Management
• Methodist College of Engineering & Technology
• Malla Reddy Engineering College
• Aditya College of Engineering
• Auroras PG College
• AU Campus Vizianagaram
• SRK Institute of Technology
• Kakatiya Institute of Technology & Sci
• Sardar Patel College
• Vishnu Institute of Technology 

Hope this helps. All the best.
