I recently took my driving test and failed on a very silly mistake.

I was thinking about it and the only way to get around that is the drive more often on the road. My instructor has only a fixed pre-defined slot for further lessons, but I would really like to drive more often than that.

Is there any way I can get this going without the instructor?

As an expat who has recently moved to the UK, I know no one with a driving license for 3 years and who would accompany me when I drive. This is really causing a hard time where I live.

I am willing to buy the insurance and car (I will need one anyway), but need a license which means more practise.
