Staff

• Majid Mirmehdi [m.mirmehdi@bristol.ac.uk] (unit director)
• Charles Kind [charles.kind@bristol.ac.uk]

Schedule:

• Lectures:
  • Thursdays 2pm in QUEENS BLDG 1.40 PUGSLEY
  • Fridays 10am in QUEENS BLDG 1.40 PUGSLEY
• Labs (starting Jan 29th). To tell what group you're in look in your Outlook calendar. You will see one of the following two slots:
  • Group 1: Thursday 1-2pm in MVB 2.11
  • Group 2: Thursday 2-3pm in MVB 2.11

Lecture recordings:

All lecture recordings eventually appear on the Re/Play system in BlackBoard afew hours after the event. Click on Re/Play on the left menu bar on the BB course webpage to find them.

Labs:

• The labs are starting on Jan 29th, so there will be no lab on Jan 22nd.
• The labs come with exercises as Python notebook. A new set of exercises will be released every TWO weeks.
• Material in the labs may appear in the exam.
• The labs are the primary route for feedback on all aspects of the course, including lectures, any question sheets and exams, not just the labs!!!!
• The lab exercises will be released in the /labs/ folder. @@ Lab4 is now available @@
• TAs: Xuan kong, Zheng Dong, Lucas Mockeridge, Harleen Gulati, Austin Long, Deep Pawar, Jeein Park

Teams:

• The Teams Team is [COMS20011: Data-Driven Computer Science 2023/24]. You should have access already through the "Teams" panel. If not, please get in touch with the COMS Student Enquiries Mailbox at coms-student-enquiries@bristol.ac.uk

Exam info:

• The course is assessed 100% by a multiple-choice exam.
• The exam will have 20 questions, worth 100 marks, and will be 2 hours. It does require a calculator (which must be non-programmable).
• If you have any questions regarding alternative exam arrangements, please get in touch with the COMS Student Enquiries Mailbox at coms-student-enquiries@bristol.ac.uk
• The exam is closed-book (so no additional materials are allowed). There will be a formulae sheet with the exam.

Past exam papers:

Year	Paper	Questions to IGNORE!
20/21	pdf	6,8,13,14
21/22	pdf	5,7,10,17,19,20
22/23	pdf	8

Important notes:

• We rejigged the course content a bit last year, and also again this year, so some questions are no longer relevant. These questions are in the "Questions to IGNORE!" column.
• The 20/21 exam was exceptionally short.
