Please could someone provide some advice?

I was travelling from home up M6 and was caught twice breaking the speed limit in a variable speed zone.

I have set out the detail below.

My biggest concern is the police service has stated they cannot deal with one offence with a fixed penalty and have referred it to the magistrates' court.

Do I need to get specific legal advice, or should I turn up, tell the truth and accept the consequence (I am worried what the consequence will be).

I have never been convicted of any motoring offence.

Received NoIP on 23/06/2023 detailing the offence: exceed a variable speed limit - automatic camera device recorded speed 68mph in a 40mph limit at 09:22 on 11/05/2023 @ M6 Northbound between junctions 13-14 (approx 2 1/2 miles after junction 13). The letter was dated 14/06/2023

Received NoIP on 25/06/2023 detailing the offence: exceed a temporary 50mph speed restriction on a motorway - automatic camera device recorded speed 60mph in a 50mph limit at 09:43 on 11/05/2023 @ M6 junction 16. The letter was dated 21/06/2023

I responded to both NIP172 forms and asked if they could consider the two offences as one offence. I received a reply dated 10/07/2023 stating that they could not consider the offences as one offence. I understand that it is their call and accept that.

I received a further letter dated 22/07/2023 regarding the offence of exceed a variable speed limit - automatic camera device recorded speed 68mph in a 40mph limit setting out that "due to the excessively high speed of your vehicle it is not possible to deal with this matter through the fixed penalty scheme. The matter will now have to be placed before the court to be heard by a Magistrate. This is the bit I really need help with.

I received a further letter dated 25/07/2023 regarding the offence of exceed a temporary 50mph speed restriction on a motorway - automatic camera device recorded speed 60mph in a 50mph limit offering a speed awareness course, conditional offer of penalty points or opt to got to court. I intend to opt for the speed awareness course but I have delayed that until I get some advice. I know that I need to respond within 28 days.

Thank you in anticipation of your help
