How to pass GCP Professional Cloud Developer certification exam?

Hello, my company recently did a purchase of courses on line live with a professor for this exam at the end we will get a voucher to try.

I recently tried the Associate with the same course provider I thought I had all the material and should be able to pass. I failed it I felt like whatever knowledge was given was not enough also for the looks of it I knew that about 60 students around 25-28 failed that is around half. Not sure if the others completed other courses.

To be honest when I was at the exam I felt dumb I had no clue what 95% of those questions where I did the entire week prior around 130 questions in practice exams that the provider gave and that I f Found online. Not a single of the exam questions were remotely similar to all the ones I did they were harder.

Do you have Materials, tips, on how to pass this Developer I have one from Coursera that was recommended to me. But besides that. What else should I do.

Ps: I was enrolled I had no choice to enroll on this Developer prior to beating the Associate, first. But I need to pass I have no choice.
