The School of Engineering at CUSAT is a difficult entry. If you're an excellent student, it will be easy to get through with only a little difficulty. But if you're an average one then it will be straining indeed. 

My friend was a topper in his branch and did quite well in the CUSAT SOE exam. His timetable included studying only for one hour a day. When you're enrolled there, you'd have much time to prepare because of the holidays and strikes. You'll be able to sail smoothly if you've scored more than 60% marks in each subject through good attendance and timely submission of assignments. 

Here are other notable points-

• If you're an average student, the four years won't be easy and you'll have to deal with a backlog or two. Backlogs are common, but if they are repeated each year then it might ruin your chances of good placements.
• If you escape failure by the end of the academic program, you'd feel proud of yourself. 
• The faculty of the Mechanical, Civil and IT departments are the ones who prepare the questions for exams, hence if you are of any branch other than these, then you'll have to work harder.
• If you take supplementary then know that it takes a lot of time in the revaluation process and announcement of the result.
• The difficulty depends on your level of brilliance because it is a bit hard to score more than 9.0 CGPA. 
• If you're dedicated, then a thorough study of the syllabus and with the reference book will help you in performing better. 

It also depends on your performance in studies, the faculty assessing your work, and your interest in the field you've chosen. If you do not get many strikes then you'd be able to excel easily.
