Practise giving an opinion, a reason and an example, then responding to another viewpoint without memorising a script.
Start with a clear answer
Before searching for sophisticated vocabulary, decide your position. State it briefly and develop it. Avoid spending the introduction repeating the question or listing reasons before the listener knows what you support.
Jeg mener at flere bør bruke kollektivtransport.
I think more people should use public transport.
Connect a reason to an example
A reason explains your position; an example makes it concrete. Use fordi for a reason and for eksempel for a relevant situation. Choose an example that supports the point rather than changing the subject.
Det er bra for miljøet. For eksempel kan vi ta bussen til jobb.
A reason followed by a concrete example; this is a practice pattern, not an official scoring template.
Consider another side
Add a genuine objection and explain how it affects your opinion. You do not have to change position. On the one hand and on the other hand help only when each side adds a meaningful point.
På den andre siden går ikke bussen ofte nok der jeg bor.
On the other hand, the bus is not frequent enough where I live.
Try it yourself
Choose a question about working from home. Give your opinion, a reason, an example and one objection. Record yourself and review coherence, not just word count. This is language practice, not a guarantee of an exam result.
