Questions & AnswersIf you have any other questions - please get in touch

What is the IB Biology (SL) exam format?

IB Biology SL has internal and external assessments: the IB external assessment is the part you do on test day and the IB internal assessment is usually a project or a presentation you have to work on ahead of time. For the external assessments: Paper 1 - multiple choice and data-based questions; will take you 1 hour 30 minutes (worth 36% of your final grade) Paper 2 - data-based, short-answer, and extended-response questions; will take you 1 hour 30 minutes (44% of your final grade) For the internal assessments: Scientific investigation; will take you 10 hours (worth 20% of your final grade) To make sure you’re prepared enough to finish in time, take a look through the IB Biology Syllabus and our free IB Biology resources that cover the most important material you should know.

How is IB Biology (SL) scored?

IB exams are scored using a combination of internal and external assessments. The IB score range is 1 to 7, with 7 being the highest. External assessments, such as the written exams, are marked by external IB examiners, while internal assessments, such as projects or oral presentations, are graded by the student's teacher and then moderated by IB examiners. The scores from different assessments are combined, and students may earn up to 42 points from six subjects, with an additional 3 points available from the Theory of Knowledge (TOK) and the IB Extended Essay, for a maximum total of 45 points.
