When you join the course you will be assigned to one of the Mentors.
This may be based on your particular needs (eg because some of the Mentors are more adept at odd-bell methods than others), or whichever of the Mentors has capacity to take on another student at the time.
It may be you have a specific roadblock you would like to overcome, so you may only need to join the programme for a relatively short time. Alternatively, if you are at an early stage and are looking for someone to help you along the journey of becoming a successful conductor, you may benefit from having someone mentoring you for a longer period of time.
There are only a certain number of Mentors, so assignment to a Mentor is dependent on one of them having time to take on another student. There may therefore be a delay before you can start. If the number of people waiting builds up, then more Mentors will be recruited. Your correspondence with your Mentor will be via your and their personal email addresses.
The Mentors themselves will not proactively chase you to find out how you are getting on. The Mentors will be reactive, not proactive. There is good reason for this. Asking the Mentors to be proactive would be asking too much, plus conducting is something that is learned at one’s own pace and when you have the right opportunities.
It also reflects that in order to succeed you will need to drive your own learning, make opportunities for yourself, then ask for help when you need it.
