GPA stands for Grade Point Average, and it is the average of your grades. The GPA is what will show up on your transcripts. There are two basic grading systems compsing of numerical and the letter grades. These are the grades that you receive in your day to day assignments and tests. These are the first step of the grading system that will make up part of your GPA. The numerical grading system is different to other places because the grading scale is from 0 to 100. Numerical grades are also broken down into a letter grade as well. Anything below a C (70) is considered a failing grade.
The letter grading system can also be broken down into a plus (+) or a minus (-). The plus/minus system exists because when it comes to calculating your GPA for the semester, the letter value matters in the decimals. Each professor has their own grading method, worry not though because each professor outlines their grading policies and guidelines in the syllabus that they hand out at the beginning of the semester. For example, a professor may say that tests taken throughout the course are worth 40% of your grade, assignments worth 50% and participation worth 10% of your overall grade for the class. Therefore, all your assignments will be averaged, then weighted at 50% of your total grade for the class.
