With a TS EAMCET rank of 18,000 and being a non-local BC-B candidate, securing a seat in an Artificial Intelligence (AI) course depends on the college. For top-tier colleges, it might be challenging as their AI cutoffs are usually lower. However, in mid-tier colleges, you have a good chance, especially with the BC-B category advantage. Focus on colleges with higher intake for AI and apply in the early counseling rounds for better opportunities.
