What are idioms?
They are phrases, words or expressions that do not have the same meaning as the
actual words used in the phrase.
In other words, their meaning cannot be taken literally.
For example, we can say:
   "I’m over the moon that I got a band 7.5 in IELTS".
Obviously you can’t take the words ‘over the moon’ literally. It does not mean the
person is standing over the moon!
The phrase is used when someone wants to express that they are incredibly
happy about something that has happened.
They are also expressions that are grammatically unusual. For example:
   "So far, so good".
This means that up until this point in time, things are going well.

How are they related to IELTS?
This is one of the criteria for achieving a band 7 in IELTS speaking for lexical
resource (vocabulary):
   Uses some less common and idiomatic vocabulary
This means that the examiner will be trained to spot if you use this type of
vocabulary. They are much less common in formal or academic writing, so they are
not mentioned in the writing band descriptors.
So forget about them for your writing (though they could be used in an informal letter
for General Training).
             ________________________________________________
Should I learn idioms for the IELTS speaking test?
They should really be quite low down in your priorities when you are preparing for
the IELTS test.
Just because they are mentioned at a band 7 does not mean you will not get a 7 for
lexical resource if you don’t use them! And if you do use some, this does not
automatically mean you will get a 7 for lexical resource!
For example, if your general use of lexis throughout the test tends to be at a band 6
level, the examiner will not give you a 7 just because you fit ‘over the moon’ in
somewhere!
Using idioms at the right time and in the right context is also quite difficult to learn.
Native speakers use them very naturally and in exactly the right context because
they have obviously been brought up with the language and they don’t have to think
about it.
Imagine you learn the phrase 'over the moon' for the test. You now have to hope the
examiner asks you a question where you can fit it in! That could be unlikely and if
you are nervous it is not something you want to worry about.
If you use them unnaturally because you are trying to fit them in the test it will
probably be noticeable. You need to be at a level where you can use them fairly
naturally. Those that can use them well in the test have not usually studied a book
and learned them but have picked them up through experience, maybe from
some time abroad or just from being quite a good speaker of English.
However, that is not to say you should not study them, but it depends on your
situation.
If you are around a band 5.5 level or lower, I would say forget about them for
now, or at least make them a lower priority. You have much more important things to
worry about.
