I have been using WhizLabs and their materials for AWS/Azure/GCP are pretty good. Passed a few exams with these already. Their exams imo is either onpar or slightly harder than the real one so it's good for practice. They even have topic-specific practice exams so even better.
This is a lifetime subscription including the practices and some training videos to all of their available courses.
Thanks ggop for suggesting I should post it here
