GL/04 Method

Every answer comes with its working.

The calculation behind the hero example, exactly as the final exam calculator lays it out. Current grade 82%, final worth 30%, target 85%.

Read the guides
  1. 82 × (1 − 0.30)=57.4points already locked in
  2. 85 − 57.4=27.6points still needed
  3. 27.6 ÷ 0.30=92.0% needed on the final
  4. 57.4 + 0.30 × 100=87.4best possible — 90% would be out of reach
