FINAL EXAM

PRACTICE EXAM

Dear students,

I hope this message finds you well. I have uploaded last year's final exam on Moodle for your practice. Please keep the following important points in mind:

1. Variations in Material: The material covered this year is slightly different to last year's syllabus. Therefore, some questions on the practice exam may not be relevant for this year's exam. 

2. Overlap with homework: Some of the exam problems from last year made it into the homework assignments this semester, so you might recognize them and already know how to solve them.

3. Increased Difficulty: I must admit that the exam I designed last year was relatively easy. As a result, please anticipate slightly more challenging questions on this year's exam.

Practicing with the previous year's exam can still be beneficial in terms of understanding the format and familiarizing yourself with different question types. Nonetheless, please ensure you take into account the aforementioned considerations while utilizing it for your preparations.

Wishing you the best of luck in your exam preparations!

Warm regards,
Florian Richter

EXAM RESULTS

Dear students,

I hope this email finds you well, and that you're enjoying your well-deserved break.

I wanted to express my gratitude for being my students this semester. Teaching this course is always an immensely fulfilling experience, and I hope you enjoyed delving into the world of combinatorial number theory with me. I hope you gained a lot from the course and enjoyed the nice theorems that we explored together.

Back to business: We have completed the grading for the final exam, and the scores are now available. I'm pleased to inform you that the results were quite impressive, with an average score of 39 out of 48 points. Congratulations to the six students who achieved a perfect score of 48/48!

I have uploaded two files on Moodle:

1. A file with solutions to the final exam. Please review it, and don't hesitate to reach out if you have any questions.

2. A table containing statistics regarding the final exam. It shows the frequency of students choosing each problem and the average score for each. For instance, the first problem was chosen by 32 out of 37 students (almost all of you), but the average score was only 5.5 out of 8, which was relatively low compared to other problems.

Furthermore, I have calculated your final grades on Moodle. When you access your gradebook, you will find the following new grade items:

1. Homework Total: This reflects the total number of points earned from the 12 homework assignments after dropping the two lowest scores. The maximum possible score is 160.

2. Homework Total (in %): This score is obtained by dividing your homework total by 160 and multiplying by 100.

3. Final Exam (in pts): This represents the number of points you scored on the final exam out of 48.

4. Final Exam (in %): This percentage is derived by dividing your score on the final exam by 48 and multiplying by 100.

5. Final Score (in %): As you know, your final grade is determined by a weighting of 25% for homework and 75% for the exam. To calculate your final score in percentage, simply add 25% of your homework total to 75% of your final exam score.

6. Final Grade: The following scale is used to assign your final grade:

6 (above 95%)
5.75 (above 90%)
5.5 (above 85%)
5.25 (above 80%)
5 (above 75%)
4.75 (above 70%)
4.5 (above 65%)
4.25 (above 60%)
4 (above 55%)
3.5 (above 45%)
3 (above 35%)
2.5 (above 25%)
2 (above 15%)
1.5 (above 5%)
1 (above 0%)

For example, if your final score is 92%, your final grade would be 5.75. If your final score is very close to the next grade then I automatically upgraded you.

I encourage you to double-check the calculation of your final grade to ensure its accuracy. Mistakes and typos always happen.

I wish you a fantastic summer break, and hopefully, I will have the pleasure of seeing some of you next semester.

Best regards,
Florian Richter
