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!
