Internal Assessment & Predicted Grades


Standard level vs high level exam weight

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

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

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

Scenario 1

  • Comparison between two students with different lab marks but the same exam marks

  • They result in different overall IB grades


Scenario 2

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 4564% which is a difference of 19%


Scenario 3

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 14 th

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!
