P1 Grade boundaries

Grade boundaries transform the number of marks into grades on a scale of 1-7. To determine the final grade, marks are scaled to percentages. 4 is considered passing. Paper 1 counts toward 35% of the final grade at SL and 25% of the final grade at HL. There are 20 marks available. See course assessment for a further overview of the weighting of components. The following grade boundaries are not official IB grade boundaries. Instead they are provided here as an indication of what can be used in class to discuss student performance.
