Hi, Nihal.

Neet exam is one of the most highly complicated and competitive exams that are happening in India.

It would have been helpful, if you have posted your category as the admissions depend upon the different types of categories.

With 155 score, your neet rank would be between 450445 - 456774.

So, the colleges that you're eligible for are 

• Sree Anjaneya Institute of Dental Sciences, Kozhikode
• Azeezia Dental College, Kollam
• Educare Institute of Dental Sciences, Malappuram
• Indira Gandhi Institute Of Dental Sciences, Nellikkuzhi
• Kannur Dental College, Anjarakandy
• Malabar Dental College and Research Centre, Mudur
• Sri Sankara Dental College, Vennecode
• St Gregorios Dental College, Chelad
• Royal Dental College, Iron Hills
• PSM College of Dental Sciences and Research, Akkikavu
• PMS College of Dental Science and Research, Thiruvananthapuram
• Pushpagiri College of Dental Sciences, Perumthuruthy

I hope this helps.
