After Jal has come back from the arcade and is standing outside Chris's flat, she is wearing a school bag (it can clearly be seen in one shot) but in the next shot it has gone, the when she arrives at her home and it is back again.
When Jal is talking to the school nurse, her phone audibly rings, however on the display it clearly says "Silent".
When Michelle is speaking to Jal in Spanish for the second time while they are outside, she says "Los exámenes son en cinco días", what should be translated as "Exams are in five days". Instead the subtitles read "Exams in two days". According to the classroom sign that is last shown "Exams start in 1 day"
When Jal is having the oral Spanish's exam, she says in Spanish's: "Dentro de ocho meses tendré a un bebé". Instead the subtitles said "In eight months I'll have a baby" it says "In SIX months I'll have a baby"
