Platform Developer 1 - Certification Goal


Please be informed that Focus On Force has recently updated this Certification Course to reflect a more modern, stylish and accessible UI.

As you may have observed, we have cleaned up the Main Lesson Page to only show the Main Objectives, Mindmap (also available in Topic pages), and Feedback -- allowing you to have a more clutter-free workspace. We have created separate Topic Pages for each detailed objective which you can access at the left hand side of the page. Upon clicking, you will be presented with the Detailed Objectives under the Section that you have chosen. Additionally, we have put "Topic Progress" indicators which could guide you better on your progress.

For mobile users:
On the Main Course Page, you will see the Lesson Table wherein Percentages and Sections are listed. On the upper right hand side of the table, you will see options to "Expand All" and "Collapse All". If you click on "Expand All", it will give you the option to pick which objective you would like to access.

    Hello Team !
    I got my Dev1 Cert on the second attempt 🙂 – I would have been able to nail the exam without stellar FoF content both lecture & exams. It is important to read the videos as they contain key elements + there fun to listen to 🙂
    The post mortem analysis of the first attempt was :
    –> my neighbourg started to play with is chainsaw when the exam started – duh
    –> I missed out on training the key Trailhead modules on Aura & LWC with coding practices (a must) – my bad
    –> After the first attempt I took an extra 10 days of prep to complete trailhead modules and focus on both Automation and Interfaces parts – reviewed the corresponding sections on FoF + exams studying provided links too
    Thank you team
    Next is sharing & Viz 🙂

    Dear Course Teacher,
    In our course, it’s said that ‘Visualforce overrides are supported for new, edit, view, tab, list and clone actions in Lightning console apps. They are not currently supported for delete and custom action.’ But in site. it’s said that ‘Action overrides aren’t supported in Lightning console apps, and are silently ignored when invoked. If a Lightning console app user triggers an action that has been overridden, they see the standard action instead. If they trigger the same action outside of a Lightning console app, they see the overridden action.” So would you please help to explain this reason for me, thanks in advance!

    1. Ian Focus Team

      Hi Joye, thanks for the inquiry. It’s true that Visualforce allows overrides for new, edit, view, tab, list, clone, and does not support overrides for delete and custom actions as mentioned here:

      Please note that you may be referring to outdated documentation: (API v41.0 – Winter 18) that talks specifically about Lightning component action overrides. From Spring 18 onwards, action overrides that use Lightning components have been supported:

      Hello Reno! Passing on the first try is great. Cheers to that milestone. It’s a pleasure for us to know that the FOF materials have been very helpful in preparing you for your actual certification. Best wishes on your next certification goals!

      Hello Marlie. We are in high hopes that our materials will help you prepare well for your examination. The topics covered in the study guides and practice exams are concentrated on the objectives in the exam outline. We recommend you taking the practice exams over and over until you obtain the highest score possible. It’s highly recommended also to reference Trailhead and other Salesforce documentation when you encounter topics that may still not be very clear to you, or you may post your inquiries here or in the feedback forums. Lastly, it’s best to gain more hands-on experience in the Salesforce platform especially if you don’t work with it on a regular basis.

      You may also utilize the MY STUDY PLAN.

      Best wishes!

      Hi, thanks for the inquiry. The actual exam contains 60 multiple-choice/multiple-select questions. So, it doesn’t require you to write code. However, it does have questions that ask you which syntax, function, block of code, etc. is the correct or best answer. So, familiarity or knowledge of the Apex programming language is an important aspect in passing the exam. More info on the exam details can be found here:
