The timetable builder puts a class's whole week on one screen, so you can plan it in one go.

## Before you start

Assign subjects to the class and section. The builder only offers subjects assigned to the class. See [Subjects](https://helpcenter.academium.com.ng/academium-sms/article/sms-subjects.md).

## Opening the builder

Open **Academics → Class Timetable**, choose the class, section and term, and open it in the builder.

## Generating a week with the Schedule Builder

The **Schedule Builder** fills in a whole week from a pattern:

1. Enter the **start time**, the **length of each period**, the **gap** between periods, and the **number of periods** per day.
2. Say **after which period the break comes**, and how long it lasts.
3. Optionally add a **room** and a **teacher**.
4. Generate. Subjects rotate through the periods, starting at a different point each day so the same subject is not always first.

If a subject already has a teacher in the timetable, generating can keep that teacher.

The result is a **draft**. Nothing is saved until you choose **Save Week**.

## Adjusting the timetable

- **Drag** a lesson to a different time on the same day. Lessons keep their length, and the times around them adjust.
- **Copy a day** to every other working day, then change what differs.
- Edit any period's subject, teacher or room directly.

Academium shows when you have unsaved changes. **Save Week** saves the whole week at once.

## Common issues

**"No subjects assigned."** The class has no subjects yet. Use the **Assign subjects** link to assign them.

**Saving is refused.** Academium explains which periods are incomplete. Every period needs a start and end time, the end must be after the start, and every period needs a subject unless it is a break.

> **Note:** Academium does not check for clashes, such as a teacher booked in two classes at the same time. Check each teacher's week in their teacher timetable.

## Viewing and printing a class timetable

Open **Academics → Class Timetable** and choose the **class**, **section** and **term**. The week is shown without weekend days. Use **print preview** to print it for the classroom wall.

[Search](https://helpcenter.academium.com.ng/academium-sms/article/sms-searching.md) for a class and use its **timetable** shortcut to get there quickly.
