Engineer

In my opinion, no, it never meant that. Just remember, class 12th is a part of life, it is not life. You can be anything you want, you just have to have a mindset with focus. Class 12th, especially in India is considered as a sign of the future growth, but it's not completely that. However, if you score well in 12th, it is good, if not, then also it's okay.
If you want to be an engineer, you can join a normal engineering college and after engineering you can write prestigious exams like GATE, ESE, etc. which will take you to new heights. You can also write exams like UPSC (if you want to be a bureaucrat) and can contribute something to society. Remember, there is an end to class 12th, but the life is endless. Never stop hoping and dreaming. So stop screwing yourself and embrace what has to come without fear and be happy and focused.
