With the rank you're mentioning you can check out these colleges accepting TSICET scores for MCA 

• Manpower Development college 
• KU college MCA department of Computer Science 

Apart from that you can get a seat in these colleges if they are left with vacant seats

• Suprabhath Institute of Management Studies 
• Vivekananda PG college 

Apart from that if you are planning to appear for any other exams for MCA then you can wait because I'm afraid the above mentioned colleges won't give you a very good career.
