CBSE 12th

Hello,
There is not a specific course that will guarantee you a job in Google. But there are many courses which will help you develop the necessary skills to get a job at Google. These along with a very good understanding of preferably one of these object-oriented programming languages: C+, Java or Python will help you immensely. You can do Data Structure related course and Algorithms are a must when it comes to job interviews.
All the best.

You can do 12th from NIOS later if you want.

Visit CBSE official site and fill the form online. Payment can also be done online.
