As I mentioned earlier in ray of hope 123, reason of not having a draw on 7th of August seems unintentional. Reason can be some techical issue. The pool data date is 2nd of August which proves that CIC was all set to have a draw on last wednesday (because usually the day of pool data is friday before the wednesday's draw).
I know the high cut off is disappointing but we can now very much expect next draw on August 21 (after 9 days). So that will bring a huge relief. However, don't expect cut off to drop drastically due to all the PNPs. But even if draw was conducted on August 7th, we knew those 600+ candidates were coming.
Don't get discouraged by all the negative people who are telling you there is no hope for 458 below this year. Nobody is CIC here. Try to improve your score but if you can't just wait patiently. No need to listen to such people and get mental stress. Only time will tell what future holds.
