My pass experience before was the same, my daughter also had to take nap in the afternoon and I try everyday not to let her sleep but not successful and was afraid it may affect her learning. I use this point and wrote to the school, but I was lucky and I wrote before register so I got the am offer last year. You can also try but the reason you provide before may not work. I guess is not a strong reason
my girl studied AM class in another PN before. i was worried before she started SHCK PM class. but seem like everything is doing quite fine and she adapts the PM class time schedule in 1-2 weeks.
