student visa-urgent help req.

[needheld]

I am applying for student visa from Pakistan, I have a few questions reguarding it and I'd appriciate it if the moderators are quick to help.
1) what is the refusal ratio for Pakistani students?
2) how long does it take for a decision to be made.

Some brief info about my application:
-I got a conditional offer( conditional being I have to complete my last year of A level with minimum of 2 Cs I already have 1 A and 2 Bs) from Trent University.
-I have paid my first year fee in advance.
-I have shown financial assests rounding to about CAD110,00, this includes properties and bank statements on my and my parents name.
-I got an overall band score of 7 on my IELTS.

Keeping this information in mind can anyone please guide me weather my case is strong enough or not?

Timeline of application:
applied on 17 june
got medical on 13 july
got my medical done on 21st july from Lahore ( I reside in Karachi but went to Lahore for medical as there werent any appointment available in Karachi till 3rd August)

PLEASE HELP!!!!
