Can anyone offer advice on delaying Casper

I signed up for tomorrow’s Casper a few days ago and haven’t had much time to prepare. I submitted my primaries first day, and the next Casper date is June 25.

It takes 2-3 weeks for schools to receive, putting my 3 or 4 Casper schools that require it into July 15 at earliest. I messed up Preview as well, so I am also taking that late June, and that is more schools I will not be submitting

I saw advice on here that Casper is not a big deal. Realistically Im not sure how true that is, why would schools ask for it if they barely consider it. It may be even more important for me as I am already fighting a big uphill battle with my 507, so I can’t afford any more low scores.

Is it worth delaying my applications for those schools to give myself a bit more time to practice? Im seeing guides and looking at the new format, and I do think it may be worth some time to at least get a hang of the question.

I took it last year and got a 3rd quartile without much prep. It is at 8pm, so I mean I have the rest of tonight and tomorrow to try to grind for it. Sometimes I am not the greatest at articulating my thoughts in high pressure, so I think I could benefit from a little more structure. I’m going back and forth
