Before enrolling yourself in any course, learn about your passion first. Research about the engineering stream and its various aspects. You can also talk to your elders to know about your interest. If you are passionate about it then only get into the engineering field.
CSE, CE, EEE, ME are considered good at CUSAT. But the placement of Safety and Fire Engineering, CSE, IT, EC is better. Other departments of CUSAT often have an off-campus placement or go for GATE.
