Chemistry Cycle B.E. / B.Tech 1st Year (Common To All Branches)

Welcome! We are here to help you prepare and pass the university semester exam

This course is great for undergraduate engineering students who feel a little lost in their subjects

We start from scratch, establish the basics and build from there.

More advanced engineering students who want a refresher or didn't quite grasp the fundamentals for the first time around would also benefit from this course.

If you're about to start an engineering program, this course is a great way to get a head start.

If you're a structures genius already, this course is probably not for you.

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In this course, we'll cover fundamental concepts and Starting with the very basics to advance, worked examples are used extensively to demonstrate the practical application of theory. 

This course is exclusively designed for the examination conducted by universities in different streams for the semester examination (Civil, Mechanical, Electrical, Computer Science, Information Science & Chemical Engineering). The total duration of the course is variable and the classes are conducted either live or recorded lectures. During classes, the students will be provided with exposure to the latest syllabus and pattern of the examination with a core focus will be to enhance concepts of topics that are covered in the examination syllabus. Special emphasis will be laid on improving the problem-solving ability of the students by providing complimentary test series to the enrolled students in the course.
