Your course’s attendance and make-up rules take priority. Here, “CSS” may mean a particular exam or course; the steps below apply generally unless your instructor provides exam-specific guidance.
1. Check the course rules and announcements
Start with the syllabus and course site. Look for the attendance policy, announcements, changes to assignments, and instructions for missed quizzes, participation tasks, or other work. Whether an absence can be made up depends on your instructor’s and course’s rules; do not assume that a missed assessment is automatically excused or replaceable.

Check for posted slides, handouts, and recordings as well. The University of Illinois’s guidance points students to course resources, while Hofstra’s guidance emphasizes checking course policies and communicating about missed work (Hofstra’s guidance on absences; University of Illinois attendance guidance).

If the lecture included a quiz, deadline, participation requirement, or material that is not available online, contact the instructor or teaching assistant. Be specific: say which class you missed and ask what, if anything, you need to do next. Hofstra advises students to contact the instructor before or immediately after class time to explain an absence and discuss missed work. That is Hofstra’s guidance, not a universal deadline; follow your own course’s communication and absence procedures.

3. Recover the lecture material
Use the sources your course provides, and check whether they cover the parts you missed:
- Recording: If an authorized recording is available, use it to follow the lecture and recover explanations or examples.
- Slides and handouts: Download posted materials and note any sections that are unclear without the instructor’s explanation.
- Classmate’s notes: Ask someone who attended for notes, especially on examples, discussion, or in-class activities that may not appear in the slides.
- Instructor or teaching assistant: Ask about gaps that the available materials do not resolve.
These sources are not interchangeable: slides may outline topics without capturing discussion, and a classmate’s notes may omit details. Follow any specific make-up step your instructor requires. The University of New South Wales recommends catching up soon; Imperial College London recommends watching a missed lecture in full within a week. Those are institutional recommendations, not a universal deadline (Imperial College London guidance on recorded lectures; UNSW guidance on attendance).
4. Review for understanding, not just completion
For a full recording, Imperial College London suggests first recalling what you know about the topic, then watching the lecture and listing questions as they arise. Revisit the relevant sections to resolve those questions. For a lecture you missed entirely, its guidance recommends watching the whole lecture rather than relying only on selected segments.
After reviewing, write a brief summary in your own words and mark the concepts or examples you still cannot explain. If you use captions, check them against the slides or notes; automatic captions can be inaccurate.

5. Take specific questions to office hours
Use office hours or a teaching assistant for the points that remain unclear, rather than asking for a repeat of the whole lecture. Before you go, review your notes and try any relevant problems. Cornell’s Learning Strategies Center recommends identifying the concepts you need help with and not waiting until the day before a test or deadline (Cornell Learning Strategies Center guidance on office hours).
Useful questions name the gap: for example, ask how a particular example connects to a concept in the slides, or which practice problem best tests the method introduced in class.

Attend the next class if you can, even if you are still catching up. UNSW advises students to catch up soon so missed material does not lead to falling further behind. If illness or other circumstances mean you miss several classes, contact your instructor or relevant student support service to agree on a manageable plan and prioritize any required work.

“CSS” can refer to different courses or subjects. Pakistan’s Federal Public Service Commission uses CSS for the Central Superior Services examination, but the title alone does not establish that this is the course you are taking. Follow your own course materials and instructor’s instructions rather than assuming that exam-specific syllabus or preparation advice applies.
