Group 4 (Science)Information Session Internal Assessment & Predicted Grades
Standard Level vs. High Level Exam Weight • SL • Paper 1 (20%) • Paper 2 (32%) • Paper 3 (24%) Total = 76% • HL • Paper 1 (20%) • Paper 2 (36%) • Paper 3 (20%) Total = 76%
Percentages converted to the IB scale • Each exam (paper 1, 2 and 3) has individual IB boundaries which dictate a number from 1 to 7 • This is a good way to estimate how a student is performing on a consistent bases (BSP = Best Sustained Performance) • Although, in the end it is the percentage from each paper by its respective weight that is used to determine the IB number from the overall 1 to 7 boundary, for example: • Paper 1 mark (25/40 = 62.5%) • 0.625 x 20 (weight of paper 1) = 12.5 • Therefore this paper 1 mark is contributing 12.5 out of a potential 20 to an overall percentage out of 100
Internal Assessment (IA) (24%) • Teachers take your best two D, DCP, and CE moderated labs plus PS (Personal Skills from group 4 project) and MS (Manipulative Skills from overall practical work) marks to tabulate your overall Internal Assessment mark • 6 labs worth 6 marks each plus 6 marks each for MS and PS totals 48 marks • Each lab mark is worth 0.5% of your final percentage contributing to a total of 24% • For every lab that is not handed in you will receive a mark of zero! • How does this affect your overall IB grade?
Scenario 1 • Comparison between two students with different lab marks but the same exam marks • They result in different overall IB grades
Scenario 2 • Comparison between two students with the same paper 1 IB grade (3), same lab mark, but different overall IB grades • This shows the gap between IB grades for an individual paper, for instance, the HL chemistry spread for a 3 is between 4564% which is a difference of 19%
Scenario 3 • No Labs = Grade drops by at least 18% from overall percentage assuming the student achieves perfect marks for MS and PS
All Labs Are Due March 14th • We will predict your grade to the best of our ability but inevitably you determine your grade in the end • Learn from your mistakes on the mocks and do the best you can on the May exams! • Good luck! • Thank you! • The Science Department
