Not sure what to do (salon job)

Okay im 15 soon , so obv still at school, but we can go to college once a week and I pick hair apprentiship & that means going to college after school for 1hr & half then when everybody go to college I go to a salon and I picked one lets call it salon1. (not giving out detail) and I started in september, its okay but its big and really busy so im not really learing much just to wash hair really and clean the salon but I’ve now finished my 2weeks work experince and I went to a different salon (salon2) And I loved it, there were time to ask question and learn more stuff and I got on really well with everybody and its just the perfect one with me, but someone already go on my course there, but they said they want to swap her with me, cause she dont do nothing she just sit there, and they said I should tell the college teacher if I can swap but I’d feel really b___y. And mean. what do you think I should do?

But I was thinking of asking if there’d take me on aswell (same day) ? What do you think I should do and if the boss say no aswelld=
