Are you wondering whether it is better to study violin for exams or study pop music? This depends on the individual's own conditions.
If you are born with a sweet voice, learn pop music. If your voice is not beautiful and your memory is very good, you can learn violin and take the exam.
However, the current grade examinations sometimes hurt the enthusiasm of children studying music, causing them not only to fail to learn knowledge, but also to hate the violin and even music. It is recommended to guide based on personal interests and preferences.
