What is a stream?
Some papers have multiple classes which we call streams, most streams are labelled with letters to tell them apart e.g. your paper might have 40 people enrolled so we make two streams of 20 people each called A stream and B stream.
You can find which stream you're enrolled into on your Enrolment Offer.
How do you change your stream?
If your programme has already started then talk to your school directly.
