Updated Grades
Written on 27.02.2026 17:49 by Valentin Huber
After some discussions and at times valid arguments from students at the exam inspection, we have decided to regrade a list of 9 questions. We have only added points. Your updated grades are visible in the CMS. We have not re-checked the exams of students, who would not have been able to reach a passing grade mathematically.
Here is a list of the changes — certain answers are now excluded from grading, so it doesn't matter if you ticked it or not:
- Questions with the word "primary" in them are now judged to be correct if only a single valid answer was given.
- For the question "When testing length-encoded input such as "<length> <payload>", how can constraints ensure that <length> is the length of the payload?", the answer "By ensuring the payload can be parsed properly" is now ignored.
- For the question "Why is it beneficial to derive input grammars automatically from a web page’s HTML structure for testing?", the answer "The resulting grammar can fill in forms and explore the application" is now ignored.
- For the question "What advantage does using abstract syntax over concrete syntax provide in fuzzing complex inputs like web queries?", the answer "It simplifies ignoring whitespace and comments" is now ignored.
- For the question starting with "Consider the new_child_coverage method in GrammarCoverageFuzzer", the answer "It computes the already covered expansions for a symbol" is now ignored.
- For the question "When fuzzing, why is it profitable to use inputs that previously caused the program to fail?", the answer "To replicate previous test attempts" is now ignored.
- For the question "Consider this grammar producing IP addresses as four octets (8-bit bytes): [...] To focus on specific octets in an IP address grammar, what techniques can be used?", only one of the two valid answers is required.
