Hi there,
It looks like you joined the site to ask this question.
I'm assuming you mean mathematics extension 2. Ext 2 tutors are generally hard to come by. I'm an Ext 2 tutor currently based in the hills district (Rouse Hill). I run weekend workshops on different 4 Unit topic and go through past papers.
I'm also in the process of producing an online 4 unit course to help students struggling.
Are you looking for private tutoring?
