      Hello Ashok! We highly don’t encourage printing the study guide as we are constantly updating it and improving it. A printed version would soon be out of date and might affect your study preparations in a not so positive way.

    I’ve gone throught the study guides and got high marks in the practice exams but I’ve failed this exam twice now. I’m not sure whether to give up. Any suggestions?

    1. Starkey

      Hi Diane, thanks for the inquiry. 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.

    Passed the exam today. As always the questions are shorter. But it took me almost all allotted time to complete the exam. In general the study guides and exam questions are top-notch, there’s little discrepancy.

      Glad that you are now JD1 Certified, Jeronimo. Congratulations, Team FOF is celebrating with you on your new milestone. Job well done!

    Hello, I completed all 9 modules of the JavaScript Developer Study Guide. I am now doing the TOPIC Practice Exams ony by one.

    For anyone who passed the SF JavaScript Exam – do you have any suggestions &/or tips before scheduling the exam?

    Also, are exam takers allowed to have writing paper during the exam?

    Thanks In Advance!!

      Hi BaSiL, thanks for the enquiry. Keep on retaking each practice and topic exam until you get the highest possible score. Please make sure you really master the objectives especially the ones with the highest weightings such as Variables, Types, and Collections (23%), Objects, Functions, and Class (25%), Browser and Events (17%), and Asynchronous Programming (13%). Do not memorize the questions and make sure you understand every concept (code, logic, syntax, structure, methods, etc..) that is covered in the study guide and as to why an answer/option is correct or incorrect in an exam.

      For online proctored exams, writing on paper or any writing material is not allowed. For onsite proctored exams though, they may provide you a pen and paper (at least in my experience). If you plan to take the online proctored exams, kindly read through this

    I have gone through the study guide which was great, i am left to tackle the questions. In this track, do we have any student who has salesforce link for trail head, which would practice coding and reading the materials. I know one part of the exam is about coding and get a superbadge, but i am not sure how i would find this. If you anybody has this information, i would really appreciate. Thanks.

      Hi Charles, thanks for the enquiry. Please check out these trailhead modules as they contain lots of code examples that you can try out locally on your machine: As for the related superbadge that requires code work to complete, you’re probably referring to the last module (Lightning Web Components Specialist) here:
