A high GPA will be a boon if:

– You completed difficult and high level courses

– It shows your drive to challenge yourself with honors level classes, capability to work hard, are willing to take initiative and you qualify academic standards

– It can be a fallback if you earn an average grade on your SAT or ACT.

How can you ensure high GPA?

A high GPA at the end shows that you have consistently managed your studies and extracurricular activities throughout your school career. You should always aim to maintain high GPA as slipping in a few classes here and there will make you work harder to catch up later on.

GPA is very important not just for college admissions, but also for scholarship applications, graduate program applications, entry into a club or organization and extracurricular activities.

How can you calculate your GPA?

There are two types of GPA: unweighted and weighted. Unweighted GPA is calculated by assigning equal importance to all grades you earned in high school, irrespective of the subject, difficulty level and other factors. Weighted GPA on the other hand takes into consideration the difficulty level of the course or subject. Higher points are awarded to courses which are more challenging. So, weighted GPA will depend on the individual college’s assignations. Here’s how you can calculate unweighted GPA:

– From year nine to year twelve, note down subject wise the overall grade obtained for each class attended during the year.

– Convert the letter grades to number using the chart above.

– Calculate the GPA of the individual years by dividing the number obtained in the above step with the number of subjects taken per year

– Combine the individual year GPAs and divide by 4 to get cumulative GPA
