What was the speed limit please?
Do you mean avoid a ban ?
On the basis of exceptional hardship?
Exceptional hardship only applies to totting I'm afraid.
This is a matter where there is a risk of a ban because of the high speed rather than totting and so it does not apply I'm afraid.
If this is 120 in a 70 mph zone then you are facing either 6 points or a ban of between 7 - 56 days.
You are at the higher end of the sentence bracket so a short ban is possible.
Although it is generally avoided on a first offence.
But even if you are banned then it will only be for a short time. Probably about 7 - 28 days.
There are no other aggravating features here.
Can I clarify anything for you?
