Hi Dear,

I will recommend you to join B.tech in marine from CUSAT - Cochin University of Science and Technology, Kochi over B.Tech. in Electronics and Communication Engineering at TKM College - Thangal Kunju Musaliar College of Engineering Kollam. If we o by rankings then CUSAT enjoys better position and is also accredited A rank by NAAC. The placement is also good there. However, join the course only if you are interested in marine field.
