is dual degree rule is now applicable in colleges. one from open and one from regular

Hello, hope you are doing well!

A double degree program, sometimes called a dual degree, combined degree, conjoint degree, joint degree or double graduation program, involves a student's working for two university degrees in parallel—either at the same institution or at different institutions (sometimes in different countries)—and completing them in less time than it would have taken to earn them separately. The two degrees might be in the same subject area (especially when the course is split between countries), or in two different subjects.

Dual Degree courses are programmes in which two degrees are awarded even though one enrolls into a single study course for a consolidated time period. The person is given a Bachelors and a Masters degree in the same programme but in less time. For example, a B.Tech and a M.Tech degree require five years for completion in dual degree programmes; however, it takes six years to complete both the degrees, if taken separately. This concept of degree was influenced by the foreign education system and was introduced in India by the Indian Institute of Technology (IIT).
