Some people suggest that it is a free choice, do you want a high GPA or strong extracurriculars? Personally, I think it is all about balance. For sure, it is important to reach your personal academic goals, but it is also vital to do activities outside the classroom. For example, are you able to finish all your homework and assignments if you are responsible for leading a yoga class every Wednesday night? Maybe? That yoga class will maybe improve your performance in the classroom? I promote activities for well being, physical training, and mental relaxation, no matter if it is bible study, ultimate frisbee, or a mentorship program. As a result, your schoolwork will improve with your experiences, and you no longer have to choose between them.
However, a high GPA is a result of hard work, dedication, and, most importantly, a high amount of gained knowledge. It truly is one way to measure your performance, skill level, and intelligence. On the other hand, it is also a measurement of how well you are able to express what you have learned, in other words a measurement of your test taking skills and how well you use the time. Therefore, I highly value a good GPA, and I think it tells us something, but I also think a high GPA alone is a useless tool for valuing a student.
Strong extracurricular activities are a great addition to a good GPA, and can both strengthen the number and prove it right. Moreover, it is also a proof of hard work, dedication, and knowledge, since it shows leadership, engagement, and how you use your time. Additionally, extracurricular activities give you a strong network which will be useful in the future when you for example are applying for jobs or graduate school. Just like a high GPA, strong extracurricular activities by itself does not tell much, it all depends on your time frame and life in general.
To summarize, both GPA and strong extracurricular activities are important, but useless on their own. The key to success in a balanced combination, where there is space for well being, physical training, and mental relaxation. GPA is vital to show your level of knowledge, while strong extracurriculars are a great source to use that knowledge. Together they are perfect, and I argue that you do not have to make a choice between them. Find your own balance and achieve your goals.
