Exam 2 will be the second use of the Computer Based Testing Facility (CBTF) for CS225. Please post all questions about the exam to Piazza. We will answer what we can!

Details on the CBTF can be found here: https://edu.cs.illinois.edu/cbtf/. This site includes information on location and general policies, so please read it carefully!

Here is what you can expect:

Grading

As per the syllabus, your performance on this assessment corresponds to 10% of your grade in the course.

Time & Place

You are responsible for scheduling your own exam time during the window of Sunday, September 25 through Wednesday, September 28. Simply go to https://edu.cs.illinois.edu/testcenter/ and choose your time!

Format

This assessment will be fairly short: 8 multiple choice and 1 coding problem (possibly with multiple parts). It will be designed to take 50 minutes.

Policies

See the CBTF page for more detailed policies. Here’s a summary:

• No hats, gloves, phones, water bottles, paper, or anything else we think might indicate a breach of academic integrity, will be allowed in your exam space.

• Please use the restroom before the exam begins.

• No questions about exam content will be answered during the exam; If you think there is a poorly specified question (or more than one), please post a private note on Piazza, and it will be handled fairly, after the exam is over.

Practice Exams

Here are some previous early exams; keep in mind that: (1) these are relatively old questions, written for paper exams; (2) this assessment is happening significantly earlier than previous semesters, so there may be content on the practice exams that has not yet been covered in lecture; and (3) most of the practice exams were taken during a 3-hour period.
