Wow! I think we’re both similar in the amount of times we had to redo lessons. The first time i booked CR was only before my prac 7 and tbh i recommend everyone to spam CR and RR if you have time because it really helps alot,kinda sad i only realise this when im at prac 7. Now im doing my prac 7 for the 4th time and all the slots for CR and RR are fully booked which is unfortunate. Imo i feel like lessons nowadays are based on luck interms of which instructor you get, i know some people that had obvious IF’s and still managed to clear their lesson while there are others who did a very minor mistake and had to redo their lesson. Im pretty sure most people in SSDC have experienced this
