Hy aashutosh,

Every engineering field have 8 semester . And four years mainly each semester Will have five of six subject with two or three labs. The syllabus copy can be downloaded from the official site of University your college is affiliated with . You can follow the guidelines by the faculties or can go completely by the books. Wishing you luck

The key to pass engineering is to the small things every day  . Just start studying from the first day itself . Dont make a burden , if you make a burden then this pile of KT's will take extra years to clear .
Make a plan about how to cover the syllabus of each and every subject. If you can't understand a subject , join a classes or learn the subject from your friends .
Organize a proper study group with friends . The one true advise is choose friends who study . Refer your class notes , as teachers tend to ask such question which he or she have already covered in lectures  ( if you are from autonomous college ) , if from any state university then mostly the teachers provide with question banks . For any subject which has more sums than theory score good marks in it , practice and practice the sums given in your books . Make on book as your main study books and other one or two as your reference book . Study from different class notes also , as they give an overall idea about to solve any sum or answer any question with different techniques.  For syllabus check the college website , as they have the syllabus uploaded and they also notify you about the syllabus. 
And the main thing is score good marks in viva as this will improve your GPA  , if you are weak in one subject, the practical marks or viva will save you from getting less GPA as you would have expected.
