Hi. Should I use future tense because of the adverb soon?
The courses will be changed soon.

English doesn't are used to convey a future meaning.

You could use any number of future structures to convey this idea, depending on the meaning you want to convey.

The courses will be/are going to be/are just about to be/would be/could be/may be/might be/should be/shall be/are being changed soon.

There are others too.

I don't understand why you are asking what verb tense to use, just because of the adverb 'soon'. Was this a test asking you to choose the correct verb tense, based on the clue word, 'soon'?

'should be changed' implies the future.
'soon' could be next hour, next week or any time in the future.

If 'soon' was replaced with 'last week' then the verb would be stated in the past: were changed, have been changed, etc.

What the hell does this mean?




You could also use the present simple for the future.

The courses change soon.

The present simple for the futureis used when something has become set or scheduled.
