Hi Nigel,
Please prepare for the CASS test by using the ADAPT manual as a reference. All questions asked in the CASS test will be similar to the ones given in the ADAPT manual. Practice mental maths questions (percentage and basic math questions involving addition, subtraction are asked). Ensure that you have read the manual at least 15 times before appearing for the test.
All the best.
Regards,
Navin Sridhar
