Hi Shruti,
Presently there is no inbuilt feature which allows you to sell a category of courses. There are two ways to handle this effectively,
1. You can create a course which basically represents the category and you can add the courses as modules within this course. Then, sell the course.
2. You can try some cart plugins from the third part plugin library and let the users add any course they want to the cart and then checkout paying at once. Although, I haven't tried this plugin personally you can still check this out,

Hope this helps.
Thanks and Regards,
Arindam
