It is true that without learning a concept you can’t implement it, but just learning a concept doesn’t mean that you can correctly implement it. Training can help you to implement the concepts you learned at your classes.
Training develops confidence in whatever we have learned. After completing training you will feel much confident about your field. If your concepts are not clear or you have confusions with them, then at the time of interview, exams or in professional life you face many problems. All experienced people always like to hear accurate to the point solution to every problem, your career depends on your sharpness, intelligence and of-course your confidence. So as much as possible, clear your confusions and get new ideas of your fields with the help of summer training, project training and become confident and sincere about your future.
