yeah they're not psychometric tests I don't think?
I got rejected for a summer job at tesco a couple of years ago because of the ****ing psychometric test in their application form. despite having worked there before. just got another application, applied again and passed. horrible job.
my mate did the numeracy and literacy tests for HSBC investment banking the other day, I imagine they're fairly similar to yours? he got our maths studying housemate to do the numeracy, which he passed despite running out of time and guessing about 5 answers, then got his english studying mate to do the literacy test. which he failed.

cheating never pays, you'll be fine (on the numeracy :thup
