goodluck to both of u..but m afraid u would not be getting the medical call and or the visa before the commencement of your classes.
i myself applied for the visa on March 25th, 2011 and my classes were starting from May 5th, 2011.... I had not even received the medical by then..hence, i had to deffer my admission to Sept. intake!
i got the medical call on June 1st.... they say, they take almost a month to issue the visa once the medical is done...
i wish you get the visa before your classes began but m afraid this is not likely to happen.
goodluck!
