Germany

Yes, Here are few colleges which I will suggest you to study B.Sc Computer Science for 1 year before moving to Germany for a Bachelor's degree in Banglore :

Since you are applying for German universities, Mostly German Universities do no except transfer of credits from most of the colleges so first you have to check for that . For the time being

1) IISc Banglore is the only college where German Universities accept the transfer of credits . 

But there should be no entrance exam so there are no colleges in Banglore where you can pursue B.Sc one year and then move to Germany.

You can find Data Science jobs in Germany if you have the right skills. The demand for data science experts is high in the German job market. When you got some work experience and clear knowledge of data science concepts, then chances are strong you get your dream job with good salary package.
