I started playing Go whilst doing a Computer Science degree
I took the liberty to err on the younger side andfrom beginner to 2d in my first 2 years, and from 2d to 3d in the next 4.
...from 3d to 4d in the 4 years since joining!
assume the age of 16 when starting the university degree:
Age & level
16: Start Go
18: 2d
22: 4d
All very reasonable for the young ages.
Even if the starting age was 17, 18, or even 19,
still very reasonable:
19: Start Go
21: 2d
25: 4d
When people talk about the growth curve in Go, the age is very important.
A vital point:
For example, later, at age 35, try starting to learn a 100% foreign language.my brain is probably getting dumber.
Let's compare the progress then to this age-16 curve.
