AA question approach

Hello, I would like to ask regarding questions such as - 'Describe procedures the auditor should perform to obtain sufficient appropriate evidence...' . It is stated that 5 marks are available - if I write 6 procedures - 5 valid and 1 not valid, will I get the full 5 marks available or I will be sanctioned for the wrong one? Or for example - again I write 6 procedures for 5marks question but only 4 are valid and 2 not valid, how many marks I will get? Thanks!
