From what age do Pakistani kids go to school?

I fail to understand how this kid that looks like she is only 1,5 year old goes to school:

I'm guessing she's going to playgroup or something like that not actually school.

Full disclosure: I have no clue how the pakistani education system works. However I do know that the affluent Pakistani's send their kids to private institutions that mimic the UK and USA's education systems.

In the UK at 3 you start nursery at 4 you start reception (which is actual school). America has a similar system. Going by this there's no way a 1/2 year old could be in school. It has to be playgroup.

there are different play group schools or montessori who cant take students at the age of 2. age 2 students goes in play group class where they do the activities like coloring painting and some learning . more play less learning. after play group three more years i m not sure about the order
nursery
nursery 2
prep
year 1 (the actual school)
