is it ok for me if i will work as a nurse and do a part time job plus do the german schooling ?

I am born on october 15, 1987 and a filipina. I am a nurse but waiting for my contract and opportunity in germany. But i failed the examination of german language last nov 27, 2014. If ever i will be given a visa in germany this 1st quarter, i am planning to have my exam here in march but i only have 2 months of studying it. . Will my luck as a student and a nurse will be ok ? Thank you for that :)
