Hey aspirant

Yes ,knowledge of economics is required. While studying BBA, you will receive one economics paper in the first year, and the years vary depending on the university. All you need to know is that there are 18 papers in total (annual scheme BBA), with economics being the only one you must pass if you are not from a commerce background. The level of economics in graduation is moderate, so there is no need to be concerned about this.

All the best.
