I want to study abroad for MBA. Which university is good for me?I am b.com 1st year student. I don't have any idea?

Since you are in first year of your bachelors, I guess you have a lot of time to do your research and apply. So good job on starting early. 

Coming towards the course you wish to pursue, you need to know that an MBA abroad requires a work experience of minimum 2 years. If you wish to pursue and MBA abroad you need to have a work experience and only then you can apply for the same. 

On the other hand, if you wish to apply for a management course right after your bachelors, you should opt for a Masters in Management (MiM). An MiM is equivalent to an MBA. The course focuses on making students capable for the management industry by teaching them the same curriculum as an MBA. The only difference is that it caters to fresh graduate and not people who have been working in the industry already. 

To get an idea about the schools that you should target for your MiM, you should checkout the FREE School Explore Tool here. It will generate a list of schools based on your profile and preferences and will make the school selection process a lot easier for you.

Hope this helps!
