Hey @SamUi Start learning by
Associate: Automation Developer Associate Training (v2023.10) Course | UiPath Academy
as @Gtzikas suggest so you get the better idea because directly jump into REFramework might be challanging as if you start now. Yes REFramework also cover in the Professional Training Course and also you get 2 project challanges .after finish these you can take the practice Test before going for the actual Certification.
cheers
