paraprofessional test

How hard is the indiana test? Our township just two weeks ago got our books and told us we have to take the test April 11-14 We have a lot of older ladies who have been out of school for many years (30+) They are worried and have been cramming the Praxis books that they bought us.  They have told us that we have two chances to pass or we have no job next year.  I would appreciate any help!  Thanks
