Coaching for mocks

Anybody got any coaching for Edexcel IAL/AS mocks for Chemistry (unit 1, 2, 3) and Maths (P1, P2, S1) near Badda, Banasree, Gulshan? I have been attending my mocks in 3g, but the place is horrible. I need a good exam-friendly environment with professional mock papers. My exams is on October.

(Pls don't recommend any coaching from 3g again)
