The IB grade in this course (seperate from, though related to, your WIHI grade) is based off of four assessments. There are two internal assessments - the HL Extension and the Engagement Activity - which are completed during the IB1 and IB2 years. The external assessments - Paper 1 and Paper 2 - are completed, in exam format, at the close of the IB2 year. Depending on your SL vs. HL decision, the assessments count for varying percentages of the overall mark. Please reference the home page or the assessment pages for specifics.
