When I was in primary 3, I did very well in my class. I get 100 marks for many subjects.
My mother asked my uncle to speak to the principal of the school and asked if I can be double promoted, i.e. go straight to primary 5 from primary 3.
The principal advised against it. So, I went to primary 4.
I am glad that I did not jump one year. It allowed me to do well in primary 4, 5 and 6 without too much effort.
I was not in a hurry anyway.
I did well in primary 6 and was accepted into Raffles Institution. If I had to go to another school it would still be okay for me.
