Frequently Asked Questions
How accurate is this IB to GPA conversion?
Our calculator uses the most commonly accepted conversion scale used by universities. However, different institutions may have slight variations. For official admissions, always check with your target university's specific conversion guidelines.
What's the difference between weighted and unweighted GPA?
Unweighted GPA treats all courses equally (1-4.0 scale). Weighted GPA gives additional points for Higher Level (HL) IB courses, recognizing their increased difficulty. Many universities consider both when evaluating applications.
Do universities prefer IB scores or GPA?
Most universities that accept IB students understand the IB grading system and will evaluate your actual IB scores. However, having a GPA equivalent can be helpful for scholarship applications and comparison purposes.
Should I include my TOK and Extended Essay points?
For overall diploma GPA calculation, yes. TOK and EE points (up to 3 additional points) contribute to your total IB diploma score, which affects your overall academic standing.
What GPA do I need for top universities?
Top universities typically look for IB scores of 38+ (equivalent to ~3.7+ GPA), but they consider the full application including essays, extracurriculars, and subject-specific requirements.
About IB to GPA Conversion
The International Baccalaureate (IB) program uses a unique 1-7 grading scale that differs significantly from the traditional 4.0 GPA system used by many universities, particularly in the United States. Converting IB scores to GPA helps students understand how their academic performance translates for university applications and scholarship opportunities.
Our calculator uses the most widely accepted conversion scale, where an IB score of 7 (the highest) equals a 4.0 GPA, and lower scores are converted proportionally. The weighted GPA option accounts for the additional rigor of Higher Level (HL) courses by adding extra points, similar to how AP or Honors courses are treated in traditional high school systems.
Remember that while GPA conversion is useful for comparison and application purposes, most universities familiar with the IB program will evaluate your actual IB scores directly. Focus on achieving your best possible IB grades, as these reflect the true rigor and depth of your academic achievement.
