Hi Sanju ,

You can join for btech ceramic and cement technology as a lateral entry(second year).

You have to sit for the national level or state level entrance exam conducted by varoius public and private Institution offering this course.

Admission procedure is based on All India level jee exam( for IIT and nit ) followed by counselling.

Some other institution have their own entrance exams such as comedk or wbjee at state level entrance exam.

Some college offering direct admission via board merit list considering marks should be at least 80% in aggregate .then you  have to go through counselling Session uopn succsgsucces clearing either any entrance exams..

Thanks.
