1. The final quiz will be on may 22.
2. Update on dropping lowest scores: since may 22 is marked as "own work" in the KTH schedule, I will drop the two lowest quiz scores before computing the average. (I highly recommend that you do the relevant problems for the final quiz before taking the exam.)

• David Sermoneta, david.sermoneta AT math.su.se
• Kim Vega, kvega AT kth.se

Starting with excercise 3 there will be a (roughly bi-weekly) quiz on the earlier set of recommended problems. See the course plans (excercises) for more information. The quiz results will give a bonus on the final exam score, see "Bonus" heading below for details.

percentage points including bonus from home work.

• A: 85%.
• B: 75%.
• C: 65%.
• D: 55%.
• E: 45%.
• Fx: 44%.

6 problem, each worth 4p. No calculators or other aids may be used.

The quiz results give up to 10% bonus on your final exam score. When computing the quiz average, your lowest TWO scores will be dropped (in case of sickness, schedule conflicts etc etc.)

Clarifying examples:

• 100% on quizzes, 50% on the exam: total score 100*0.10 + 50 = 60%.
• 50% on quizzes, 75% on the exam: total score 50*0.10 + 75 = 80%.

Bonus validity: the bonus will be counted at the first ordinary exam, and the first ordinary re-exam.
