Hello Aspirant,

Registration form is the form which is used to register the candidate in the records of college but admission form is the form which is to be filled by the student to take admission in any particular field of interest (course) offered by that college.

Different colleges have their different criterias for taking admissions for e.g., some colleges have single form which is to be filled for getting admission into that college and some colleges have two or more forms. Similarly some colleges can consider registration form for admission but some colleges might require some other forms also. So it solely depends on the college authorities.

I hope this information cleared your doubts.

Good Luck!!
