Hi Koramutla.

Congratulations for completing Class 12 with Science. I'm unable to fully understand your query from the your question and would request you to mention it more clearly.

From what i can guess, it seems that you are asking about the couses available that would help you to secure a job as early as possible. Well, in that case, ther's no such course that can guarantee a job at the earliest but there are courses that requires a Bachelor's degree for entry level positions. B. Com, BCA Computer Application), B. Sc. IT, etc are some of them that requires 3 years for its completion and you can get employed with a Bachelor's degree.

For any other query, feel free to ask in the comment section.

Have a good day!
