Can anybody guide me regarding the ECTS system for B.COM students. A lot of Universities require a minimum of 180 credits(3 years) but B.COM gives 150 credits(3 years).

my_qualifications: 3rd yr Bcom General Student who wants to study abroad(Germany most likely) I was thinking of applying to many Universities but they all have requirements of 180 credits. I checked at my University (Osmania University, Hyd) and it gives a total of 150 credits for 3 years. For context, my brother has done Btech at Manipal and he attained some 170 credits in 4 years. So can anyone please guide me as to how the ECTS credit system works in general and especially for B.COM? I'm extremely confused. Any information will be appreciated. Thanks
