Hello Muskaan, there are no specific benefits of giving the UGAT examination, it's like any other national level entrance test for admission into Business- schools. I can understand your concern of getting into a good college. But if you want to give this exam, then it increases the possibilities to get into a good college. Also, if you may like you can give more entrance exams for getting into management courses. 

 UGAT BBA 2019 is an Under Graduate Aptitude test, which is conducted by All India Management Association (AIMA). The examination is conducted to assess the aptitude and general intelligence of the candidates for admission into undergraduate programs like integrated MBA(IMBA), BBA etc. You can apply for the exam through both online and offline modes. There are around 60-62 institutes participating in the process (i.e., they accept the UGAT score 2019 for admission). While applying you are given a choice to choose five options from a variety of colleges.  

Few top colleges that participated in UGAT 2018 are as follows:

1. New Delhi institute of management, New Delhi

2. St. Xavier's College of Arts, Science and commerce, Goa

3. Goa university, North Goa

4. Jagannath institute of management sciences, New Delhi

6. KIIT School of Management, Bhubaneswar, Odisha

7. SS Dempo College of commerce and economics- BBA department, Goa

8. Don Bosco College, Goa

9. Rosary College of Commerce and Arts, Goa

10. Rourkela Institute of Management Studies (RIMS), Odisha

I would recommend that you must utilise every possible opportunity to the fullest.
