What Is GPA and How to Calculate It?

Firstly, let’s demystify GPA. GPA stands for Grade Point Average and is a numerical representation of your academic performance in a course or an examination. In the global academic landscape, two common GPA scales are the 4.00 and 5.00 scales. These scales are used to evaluate your grades, whether they are presented as letter grades (A-F), numerical scores (1-100), or percentages (1%-100%).

In Nigeria, grades are typically assessed on an A to F scale or 1 to 100 scale, which is then converted to a GPA on either a 4.00 or 5.00 scale, depending on your school or country.

What Is CGPA and How Is It Calculated?

CGPA, or Cumulative Grade Point Average, differs from GPA. CGPA represents the cumulative GPA of a student over a specific period, often a semester or term. On the other hand, GPA usually focuses on a single course or exam. When you hear people talk about their overall academic performance throughout their entire academic journey, they’re referring to their CGPA.

Why Calculate GPA as a Secondary School Student?

Many secondary schools in Nigeria now use the GPA grading system. This transition from traditional grading systems to GPA is beneficial as it prepares students for the GPA-based assessment used in higher education. When applying for admission to universities, you’ll need to provide your GPA, making it a fundamental skill for secondary school students.
