The way I see it, these three are outdated. By the time I started working as a Salesforce developer, the company I worked for had already stopped using them and was migrating the logic to flow. I don't see any utility in learning them. So, for my PD1 certification, can I ask SF not to include questions from these topics? If yes, how? If not, how long will I have to postpone my certification exam to not get questions on these topics?
There is just so much to learn that I would rather postpone my exam than study outdated stuff that I will probably never use.

Hello @Roman Regmi, you cannot arrange the certification exam the way you want. However, make sure to follow the certification guide. For information, certifications are regularly updated by Salesforce, and take into consideration new features / capabilities (more flows for example). But you can still implement VF pages in Salesforce. Eric
