Certification Practical Exam failed

Failed on practical exam first attempt with 69 points. Silly me I left some output and write range to check but upload with those hard codings etc.
I assume second attempt will give another random question that is quite different than first. Any advice?
Thanks

@Attila1

yes, the Certificate practical exam will give random questions based on ACME application and sometimes there will be some changes in filters only.

Hope you will clear the exam this time.

All the best.
