they will sent the same that there is update to your account. and you can see it to your Gckey account the decision. i received my refusal within 2-3 months. no did not do medical since it not required.
I see I can't see any updates on my GCkey account because I couldn't link my paper based application online even I tried many times that's why I keep on depending on there email to me whatever be the updates. The last email that I received from them was last Sunday that my application has been finalized and the decision letter will be sent to email soon. Until now I haven't received anything. As I have said I'm done with my medical as per there request last 5th of May, I received the medical request form from them 25th of April the clinic uploaded my medical result 10th of May since then until June I haven't heard anything from them even I sent many web forms, but this July I received 3 emails and the last was that my application has been finalized.
