I’ve booked a practical lesson with less 10 hrs of driving ?

I’ve booked a driving test @ my parents local test centre , which is an 1 hr and half away from my university which I’m back in about a month I plan on doing the commute 2 - 3 times a week however at the minute I plan on doing about 3-4 if I can find an instructor which there are many since a lot of the rates now are 35hr where my parents live compared to my uni , however I’m bit worried I may have rushed into things should I cancel my test ? Until I find an instructor I’m comfortable with or should I just do a semi intensive course , also I’ve forgotten many rules of the road and was thinking of downloading the highway app to practice would that be useful?

Any advice I’d appreciate it
