Science

Scope is something which is very relative. If I talk about engineering, the branches that are having scope right know may not have scope after the completion of B.Tech and if you ask me personally then don't go for engineering because it has gained the saturation level and you would struggle to get the job here. So, firstly think of the field which you have interest in and then you can check out the scope from the websites like Shiksha and others.
Some examples:
If you have interest in drawing and are creative, you can go for B.Arch or interior designing.
If you have interest in computer, you can opt for BCA and you can think ahead.
If you want to go for management then you can go for BBA
you can go for B.Sc if you like science and not the applied science used in engineering.
You can also go for hotel management if you have managerial and leadership skills.
You can also join Indian Army for ground duty via exams like NDA.
Note: Don't follow others and make sure your decisions are not influenced by other.

Master's degrees from Germany are usually categorized as either consecutive or non-consecutive. Those in the first category are designed to build on the academic knowledge gained during a related Bachelor's degree. Non-consecutive programs tend to have a greater focus on professional development often requiring applicants to have both an undergraduate degree and some relevant work experience. Most of the Master's degree in Germany take four semesters (two years) to complete. Though some are shorter or longer. To apply for a Master's degree in Germany, the first word to get to grips is HZB meaning higher education entrance qualification. An undergraduate degree completed in another country is usually accepted as a suitable HZB for admission to a Master's degree in Germany, but specific requirements will vary depending on the course, institution and where you've previously studied. For some Master's degree courses, applicants are required to have earned a minimum number of credits in a specific field of study. These conditions are set by the department offering the program.
Applications for Master's degree programs are either submitted directly to the university or via the online portal called Uni Assist.
The specific documents required and application process will be set by each institution, but you'll typically be asked to submit an official copy of your academic qualifications, a passport photo, a copy of your passport and a copy of language proficiency exam results (if applicable).
