Hello Aspirant. I hope you are in good health. Its really difficult to predict exact range of rank where you may end up as cutoff trend and common rank list varies significantly each and every year. However, as per your results, your rank may be around 16414. If the exams are simple/hard then actual ranks can differ in a higher margin. Moreover, you haven't mentioned your caste so I assume you are a General (State Merit) candidate. According to previous years' data, you may have good chances in few public/government institutes such as:

1. Sree Chitra Thirunal College of Engineering, Thiruvananthapuram
2. Government Engineering College, Wayanad
3. College of Engineering, Chengannur
4. Government Engineering College, Idukki
5. LBS Institute of Technology for Women, Thiruvananthapuram
6. College of Engineering, Adoor
