Bro I have a score of 453 as well.
But am just 25 so I have 5 yrs time before the score goes low for me that way.
But I got into the pool in March.
Only if I entered like in Dec or something I would have got ITA long time ago.
Somehow currently my life is at its worst time period.
and was hoping Canada will take me away from all this mess. But even thats not happening.
