I am planning to pursue MBA from Germany ( 1 to 1.5 year course). I am looking at GISMA,CBS,SRH Berlin & IUBH. Are they good choices for September 2022 intake?

I imagine you are using a recruitment consultant paid by those schools. Is there a reason why you are focussing on for-profit schools? Do you have any goals? Why German schools? 

I'm not sure I would recommend any of these schools to many candidates. 

If you are looking in Germany, with the goal of working in the country after graduation, you should already speak German at a near-fluent level. And if you already do, there are better options than one of these degrees, at least in terms of making a transition into the country.
