Momi i asked the iso officr they said we can join before DNE date that is 17th sep ...
I suppose usually you can join within 2 weeks of the start date of the class. If you've already paid the fees and registered for the courses then you may need to keep an eye on the add/drop deadline because you'll need to get the refund on your money just in case you don't hear back from the high commission.
I am not sure if the 2 week window I mentioned above is through university. Its usually the immigration officer at the border who is picky with the dates. Don't panic, wait until the first week of September. And, keep in touch with your admission consultant at university.
