Ah, CF's PreCATs.
I gave them last year. They were very very tough

. And the best thing was that i used to get percentiles in the range of 99+ even for very low scores.
Anyway, don't get too bogged down if you find them very tough. CAT is generally much easier

And yeah don't bloat up your pride after looking at the percentiles

They simply are not the right indicators. Treat these tests just as practice for different kinds of problems.
ATB everyone
