Usually parents and students only know the IB number scores but do not really understand besides the number scores, IB also has percentage scores and how to calculate IB percentage scores and their deep meaning.
💯 How to calculate IB score
IB students will be graded on a scale from 1 to 7. The highest score for each IB subject is 7, the perfect score for 6 subjects is 42. EE, CAS, TOK will have a total of 3 points. IB scores are recognized and appreciated by many universities around the world, especially in the US and Europe.
For the IB, students will choose 6 subjects: the 5 subjects in each group from 1 to 5, the 6th subject is an elective subject in the Art subject group, students can study the 6th group or 1 subject in the 5 other groups to replace.
Each subject will have an Internal Assessment that is graded by the school and guaranteed by the IB Organization to synchronize the scores, the final exam at the end of year 2 is graded by IBO (External Assessment). Does it affect how to calculate IB percentage scores?
🎯 How to calculate IB percentage scores?
IB percentage scores will be provided in addition to the regular number grades. It is important to note that the percentage score is not the total percentage of marks achieved for the course, but rather a scale in the system that measures how many students get high scores, how many students get average, and how many students score low? The percentage points will appear in the results report and not be mentioned in the actual certificate.
For example, a student scoring 7 would be placed on the 99-100% percentile scale, a student scoring 3 would be on the 70-76% percentile scale of the rest of the students.
The IB percentage scale is not applied to students who are not graded (Failing Grade). Below is a detailed table for the IB percentage scale
| IB Grade | Converted Percentage Grade |
| 7 | 99-100 |
| 6 | 92-98 |
| 5 | 84-91 |
| 4 | 77-83 |
| 3 | 70-76 |
| 2 | 50-69 |
| 1 | Failing Grade |
🏫 Experience of getting 7 points in IB subjects
- Take notes of important knowledge: Concentrating on taking notes when the teacher teaches is one of the important points to help you build a solid foundation of knowledge, making it easier for you to learn more and have more time to find out. understand new knowledge.
- Effective study plan: Due you need to spend time on 6 subjects, you need to plan your time division for subjects to ensure a balanced time will help you study better.
- Every day a question to improve: usually ask questions to find solutions through which will stimulate creativity, problems solving and it helps us form good habits and be positive.
- Motivate yourself: When successfully solving a difficult exercise, you should reward yourself with a few minutes of rest, sometimes a small gift as a motivation for your own achievements.
🎓 What is the IB Grading Scale?
IB has a grading scale to assess their students, with a total score of 45. To obtain the diploma, a student must earn a minimum of 24 points as well as pass the minimum requirements for the core of the program. Students take six subjects in IB, with each class worth seven points of the total grade. So, the total points you can earn from your classes is 42, with the leftover three points coming from the core mentioned earlier.
IB grades students based on a combination of school-based internal submissions such as research papers (IA) and numerous external examinations, with the number of exams per subject differing depending on whether or not the student opted for an HL or SL version of the class. If you don’t submit your IA, you’ll instantly become ineligible to receive the diploma, but receiving a failing score on your IA doesn’t completely ruin your shot at the diploma.
Each subject is graded on a scale of one to seven, with seven being the highest grade possible. Each examination is made up of at least two papers per subject, but usually contains more. For the sake of a better explanation, let’s talk about exams using IB Biology as an example. The IB Biology (SL) exam is broken down into the following parts:
- Paper 1 – Multiple Choice Questions
- Paper 2 – Short Response and Extended Response Questions
- Paper 3 – Section A contains data-analysis questions; Section B contains questions regarding one of the extended options topics students must choose from.
- Practical Work (IA) – This usually refers to internal assessments, like experiments carried out in school, with the results sent to IB in the form of a research paper for grading.
Each paper has a different percentage of weighting, but note these values can and usually will change every year. For IB Biology, the breakdown looks like this:
- Paper 1 – 20%
- Paper 2 – 40%
- Paper 3 – 20%
- Practical Work (IA) – 20%
Calculating your final grade after these exams would use a formula like this:
Final Grade = (Paper 1 Score) * 20% + (Paper 2 Score) * 40% + (Paper 3 Score) * 20%
+ (Practical Work Score) * 20%
Next, take the percentage scored and use an IB grade boundary set to see where it falls on a scale of 1 to 7. These boundaries are usually shared with your school from IB themselves for each examination season. This process is repeated for every subject IB has to offer, but the number of paper and their weighting differs, but you can expect nearly all science subjects to be similar or the same as the biology example.
