Short answer: list every lecture you missed, rank them by how much they matter for the exam, and catch up on the most important ones first. Watch recordings actively: pause after each section and recall the main points, then turn them into questions you answer again later. Go to every lecture from now on so the backlog stops growing, and use office hours or friends for the parts that still do not make sense.
Why attendance matters (and why recordings are not a full fix)
A meta-analysis by Credé, Roch and Kieszczynka (2010), pooling dozens of studies of university students, found that class attendance had a strong relationship with grades, stronger than any other predictor they knew of, including entrance test scores and study habits. Attendance is not magic in itself, but going to lectures keeps you up to date and makes it hard to drift.
Recordings help, but they are a weaker substitute than they feel. Edwards and Clinton (2019) followed a cohort before and after lecture capture was introduced on a course. Attendance dropped once recordings were available, attendance predicted better results, and watching recordings was not linked to better attainment once attendance was taken into account. The authors stress that recordings are valuable for many students; the risk is relying on them instead of keeping up.
The lesson is not to panic. It is to catch up in a way that does more than press play.
Step 1: triage the backlog
- List every missed lecture with its topic.
- Mark its weight. Use the course outline, past papers and anything the lecturer said about the exam. Topics that carry more marks, or that later topics build on, go first.
- Check what you already know. Skim the slides for each one. If a topic is familiar, a quick self-test may be enough.
- Plan it across days. Two or three missed lectures a day, alongside current ones, is sustainable. Ten in one night is not. Our revision timetable guide helps here.
Step 2: catch up actively, not passively
Whether you use the recording, the slides or a friend's notes:
- Start with the slides. A quick skim gives you the structure before you watch.
- Watch in sections. Pause at the end of each topic and write down, from memory, the key points.
- Speed up the easy parts only. Normal speed for new or difficult material; faster for repetition and admin.
- Note your questions rather than getting stuck. Take them to office hours, a tutor or classmates.
Our guide on studying from lecture videos covers more of this.
Step 3: test yourself on what you caught up on
Catching up only counts if it is still there in the exam. After each lecture, write a handful of questions on its key points and answer them the next day, then a few days later. Answering questions strengthens memory much more than rewatching (Roediger and Karpicke, 2006), and spreading those reviews out makes them last (Cepeda et al., 2006).
When you are already behind, writing questions for every lecture is the step that gets skipped. Ace can do it from what you have: upload the slides or PDF, or paste a YouTube lecture link, choose the topics, and it writes practice questions from that material only, with the line each answer comes from shown underneath.
Step 4: stop the backlog growing
- Go to the next lecture, even if you are behind. Current material is easier to keep up with live.
- Do a short review the same day, even five minutes of recall.
- Find a study partner in the same module and quiz each other weekly.
- Tell someone if something bigger is going on. If you missed lectures because of illness, work or your mental health, your university's student support can often help with extensions or adjustments.
Frequently asked questions
Is it too late to catch up?
Usually not. With a few weeks and a focused plan, most backlogs are manageable. Prioritise the heaviest topics and test yourself rather than trying to rewatch everything.
Should I watch recordings at double speed?
Only for parts you already understand. For new material, normal speed with pauses for recall works better.
Can I pass without going to lectures?
Some students do, but attendance is strongly linked with results across many studies. If you cannot attend, make sure you are actively studying the material each week.
What if there is no recording?
Use the slides, the reading list and a classmate's notes, and ask the lecturer what the key points were.
