I am also taking lessons for my 2B licence, at the age (mid 40s). It is not easy.
I started in 2019, disrupted many times due to covid, personal and work matters.
I am now waiting for my test date this month.
I have failed many times, fell of the plank, miss the timing, wobble..... but I keep trying and I really hope that I can complete this course and get my license.
