Lectures
The Lectures tab is every lecture of a course, past and future. Each one opens onto its own page with the files handed out, your attendance and the replay if there is one.
The Lectures tab is the full lecture list for one course. It is not a timetable of the week, like Schedule; it is the whole run of the course, from the first lecture to the last.

What the list contains
Every lecture you are personally assigned to, with no cut-off at either end. A course that ran for a year shows all of it, and cancelled lectures are included rather than quietly dropped.
The list is your lectures, not the class's. If a lecture was arranged for part of the class only, it appears for the students who were put on it.
How it is grouped
A lecture running now is pinned to the top
It sits above everything else in its own panel, marked Live now, and the date is drawn in the course colour. Selecting it opens the lecture, where the Join button lives.
Then Upcoming, soonest first
The soonest lecture that has not been cancelled is tagged Next. While something is live, the pinned panel at the top is the one to look at and the Next tag steps aside.
Then Past, most recent first
Each month in Past also counts its recordings next to a play icon, so you can see at a glance which month has replays worth going back to.
Inside each section, lectures are grouped by month and every month collapses. The month holding the next lecture opens by default and the rest stay shut, so a year-long course opens on the part you actually need. Months you open yourself stay open.
Reading a row
| Part of the row | What it means |
|---|---|
| Big date on the left | The weekday and day. It is drawn in the course colour for the next lecture and for one running now |
| Title | Only shown when the teacher named the lecture. Most rows in a repeating course have none, and the date identifies them instead |
| Time | When it starts |
| Online | It happens in EasyClass rather than in a room |
| Room name | Where to go. A row can show both, which means the lecture is running in a room and streamed |
| {n} materials | Files attached to this lecture |
| Recording available | A replay is ready, in the course colour |
| Cancelled | It was called off |
| Coloured chip | Your attendance: Present, Late, Excused, Absent or Expelled |
A row with no chip is attendance your teacher has not finished
Attendance shows up once your teacher has finalised it, which can be well after the lecture itself. If you need to know where you stand before then, ask them.
Opening a lecture
Selecting any row opens that one lecture. The course header stays where it is, so you are still visibly inside the course.

The rail on the right is headed by the date, then the time range, whether it is online, the room, the teachers taking this particular lecture, and your attendance once it is final.
The main column holds what the lecture left behind, in this order:
- The recording, when there is one.
- Assignments set from this lecture, with their deadlines.
- Materials handed out in it. These are the same files that appear on the Materials tab, where they are labelled with this lecture's name.
A lecture with none of the three says Nothing's attached to this session yet.
Online lectures
Some lectures happen inside EasyClass instead of a room. They are the rows marked Online, and they are the only ones you can join from the app and the only ones that can leave a replay behind. Everything else on this page applies to them just as it does to a lecture in a room.
Joining one while it is live
Online lectures open fifteen minutes before the scheduled start and close at the scheduled end. Outside that window there is no button anywhere, on any screen, because there is nothing to join yet.
Inside the window, Join appears on the lecture's page, on the course Overview under Up next, on the course card in My Courses and on Home. They all lead to the same door.

Waiting for Moderator
The meeting will begin when the moderator joins. Checking every few seconds...
Too early
Meeting Hasn't Started, with the scheduled time. Come back inside the fifteen-minute window.
Waiting for the teacher
Waiting for Moderator. The lecture exists but nobody has opened it yet. The page checks every few seconds and moves on by itself, so leave it open rather than reloading. If the connection drops it says Connection issue. Retrying... and keeps trying.
Ready
The lecture's name, your teachers, and Join Now. Selecting it takes you into the room.
Ended
Meeting Ended, with the time it finished. If it was recorded, the replay turns up on the lecture's own page.
Some schools host their online lectures elsewhere
If your school runs its online lectures on an outside tool, Join sends you straight there instead of showing this door. You may be asked to sign in to that tool, and its recordings, if any, live there rather than in EasyClass.
Watching the replay afterwards
Replays play in the page. Nothing to download, and nothing to install. A lecture recorded in more than one sitting arrives as Part 1, Part 2 and so on, as buttons under the player, in the order they were made.
Leaving the tab open for hours can break playback
If you come back to a tab you left open half the day and the replay will not start, use Retry in the player. That is almost always all it needs.
Recording is decided per lecture, when it is created, so an online lecture only has a replay if your teacher turned recording on for it. A lecture with no Recording available tag has none to find, and there is nothing on your side that can request one afterwards. Ask your teacher.
One exception is a lecture that has just finished: a long recording takes a while to become available, and the tag appears once it is ready.
Cancelled lectures
Cancelling does not remove a lecture. It stays exactly where it was in the list, with its title struck through and a Cancelled chip, so you can tell that something was planned and called off. A cancelled lecture never gets a Join button, never gets the Next tag, and never pins itself to the top even if its scheduled time is right now. Opening it says This lecture was cancelled.
Lectures you were invited to
You can be put on a lecture belonging to a course you are not enrolled in, for instance a guest lecture. Those open normally and their replay plays, but the parts that depend on enrolment, such as the lecture's assignments, are left off.
Troubleshooting
The button exists only inside the join window: from fifteen minutes before the start until the scheduled end. Before that there is nothing to join; after it the lecture is over. The button also never appears on a cancelled lecture, or on one held in a room.
Use Retry in the player. A tab left open for hours reliably fails and reliably recovers that way. If retrying keeps failing, the recording may still be processing, which can take a while after a long lecture.
Recording is set per lecture before it happens, and a lecture in a room is not recorded. If the row has no Recording available tag, there is no replay to be found. Your teacher is the only person who can record one.
Lectures are assigned to students individually. If you were not put on that one, it does not appear in your list, and their link to it will tell you it is not available. That is also the message you get for a lecture in another class's version of the same course.
Check whether it is marked Cancelled. A cancelled lecture stays where it was when it was called off, so one whose time has now passed sits at the bottom of Upcoming instead of moving to Past.
Attendance is recorded by your teacher and cannot be changed from your side. Once a chip shows, it is their final entry for that lecture. Contact them if it is wrong, and note that repeated absences can be flagged against a limit set by your school, which you can see on the course Overview.

Inside a course
Opening a course gives you its own space, coloured like the course itself, with seven tabs and an Overview that summarises the whole thing in one screen.
Course materials
The Materials tab is every file shared with your course, whether it was handed out in a lecture or attached to the course itself, searchable by name and downloadable in one selection.
