Strategy to Ace Prerequisites and the Platform Developer I Certification!

After deciding to appear for the exam, it is time to gather information about it and consider what steps you will take to ace it. Once you have a concrete timeline, think about how you will integrate a sound study plan around the rest of your responsibilities – work/home balance, etc. Having a concrete date to study will help you stay motivated.

Below are some details about the exam and study materials:

  • 60 multiple-choice/multiple-select questions – 105 mins
  • 68% is the passing score
  • The exam Fee is $200 plus applicable taxes
  • Retake fee: USD 100, plus applicable taxes as required per local law
  • Platform Developer I Exam Guide
  • Exam Outline 
    • Developer Fundamentals: 23%
    • Process Automation and Logic: 30%
    • User Interface: 25%
    • Testing, Debugging, and Deployment: 22%

If your goal is to become a certified Platform Developer I, I highly recommend starting with Platform App Builder certification. While preparing for the Platform App Builder exam, you will get a solid understanding of data models, declarative automation, and user interface design capabilities.

Once you’re done with Platform App Builder certification, start upskilling your skills by starting the Platform Developer I certification track.

What you Need to Know to Smoothen your Journey

One of the things my Driving Instructor used to say, one can’t learn the drive by sitting behind the wheel. He also often said, learning to drive a car takes time – you don’t just become a good driver overnight; you learn it through practicing behind the wheel for many hours. The same applies when you start learning to program. You may learn the best practices by watching videos on YouTube or reading books/articles. To become a developer, you must start writing code independently.

To ace the Platform Developer I certification, you must demonstrate your knowledge, skills, and experience in building custom applications on the Lightning Platform. There is no shortcut to success. Read and practice as much as you can.

  1. Let’s start from basic – Even though you haven’t written any code and want to become a Platform Developer, the following steps will help you to achieve your goal.
    1. Spend 1-2 hours daily writing and practicing code. You may want to check out this article to get some idea: Creatively Decode Your Salesforce Developer Journey.
    2. Learn how to write basic algorithms or Pseudo Code. You can always look up algorithms and sample code in Salesforce-provided documents. But Learning them will expand your mindset and how you tackle any problems.
      1. An algorithm is nothing but a mention of steps to solve a problem.
      2. Learn Object-oriented Programming from YouTube video Java Tutorial for Beginners.
      3. If you are overwhelmed by lots of information, it may be time to take a step back and refocus your attention on learning Apex code directly.
  2. Start your Apex journey from David Liu’s course. Don’t just watch the video. Make sure to practice the exercise in your developer org. Use this link to signup for a free developer edition org.

Remember

  1. Do not stress too much about remembering syntax. You will forget most of it anyway.
  2. Learn how to write code. Focus on improving problem-solving skills.   
    1. Start writing Pseudocode instead of writing Apex code directly. It means solving the problem in plain English (Pseudocode)! And, only then, write the code. 
  3. Master a good debugger. Think of it like solving a detective novel!
  4. Do not forget to unit test your code. Most of the time, your code will always be buggy.
  5. Do not think highly efficient code is always good. Sometimes, the development cost outweighs it.
  6. You’ll always make mistakes. Be willing to accept it and learn from it.
  7. Start using Visual Studio Code (or an IDE) and learn most of the shortcuts. The learning curve might be high. But once it becomes muscle memory, your productivity will be improved. 
  8. Make friends with a professional programmer and see if they can take a few minutes to review your code. 
  9. Don’t give up on yourself – I’ve met many self-taught programmers. They all had one thing in common – they never gave up.

Conclusion

If you have good hands-on experience with all the above topics, passing the exam will be a cinch, and you will be able to earn the much-coveted Platform Developer I certification! However, if you do not have enough experience with Apex, SOQL, Lightning Web Component and plan to become a Platform Developer I. I suggest you draw a 6-9 months plan (finish the above ApexAcademy, Trailmix, and Instructor-led training) to prepare for it.

I hope that you find these tips and resources useful. If you put the time and effort in, you will succeed. Happy studying and good luck!
