Questions & Answers about Der Test beginnt um neun Uhr.

Why is um used for “at” here? Could I say am or bei instead?

German uses um for exact clock times: um neun Uhr = at nine o’clock.
Use am for days/dates or parts of the day (e.g., am Montag, am 9. Mai, am Morgen), and bei for “at/near” a place or event (e.g., bei der Schule, bei der Prüfung). So here only um fits.

Do I have to say Uhr? Can I say Der Test beginnt um neun?

Yes, um neun is fine and common in speech. Uhr makes it a bit clearer/formal and is standard in writing. With half/quarter expressions you usually drop Uhr: um halb neun, um Viertel nach neun.

Why is Uhr singular in neun Uhr?

Because Uhr here means “o’clock,” not “clocks.” It stays singular after a number: Es ist neun Uhr, um neun Uhr, um neun Uhr fünf.
