Throughout my training, I took several CR and RR. They do help me to remember the needful skills.
Although RR was expensive than CR, but I could revise the circuit after 4 rounds of road revision.
I get to talk to many students since it's more relaxed, and some of them shared with me their mistakes which I also started to learn from them. Riding is generally more friendly because we get to speak to other fellow riders who are next to us.
Sometimes during the revisions, I get frustrated at myself for making fundamental mistakes, even when I made them previously. Each time I reproach myself to improve and never to make the mistakes.
