Hi Thiruttani 

Yes ,you have less chances of getting seat in mbbs ,in Sri Venkateswar Medical College .As last year's cutoff of this college was 433 marks and as you said ,you have secured 293 marks .

Even if we'll consider other government or private college in andra pradesh ,according to last year's cutoff ;there are less chances of getting admission in any of those colleges .As approx cutoff in every college is till 330 marks or so.

Still don't lose hope ,go for the counselling .

All The Best
