My Strategy for Passing the Salesforce Platform Developer I Certification

Prior to getting started, I recommend you create a free Salesforce Developer Account, so you can use a free developer instance to learn salesforce, and you’ll have access to free courses on Salesforce Trailhead. I would recommend you to study all the trailhead modules related to Developer 1 exam. There are two trails from Salesforce, that are listed below. It will give you a complete picture of programmatic development. 

Once you’ve familiarized yourself with the content, I’d recommend the Salesforce trail: Platform Developer l Certification Prep. In this trial, you’ll be able to take some practice questions that will help you to understand the patterns and types of questions that are asked on the exam. Also, read the Flashcards carefully, sometimes the wording of the questions are a little tricky, so take your time when you’re going through the flashcards. If you’re stuck on any questions, try to go back to your development org and implement the solution for a full understanding of the concept. 

During my exam preparation, I tried to focus more on the highly weighted topics rather than the lower weighted topics. This may or may not work for everyone, but I’d also recommend focusing on the topics that you feel the weakest in. 

Study Materials 

The self-study materials I recommended for this exam are as follows:

Guides to getting started with Apex, Visualforce, SOQL, and SOSL

Additional Study Guides & Key Topics

If you need additional study materials and practice exams, Focus on Force is a great resource. While it is not free, it’s a great resource. The practice exam will provide you with explanations as to why you have answered a question wrong, as well as allow you to retake the exam as many times as you need. 

Below are the key topics for the exam. I’d recommend having a strong understanding of each of these topics prior to taking the exam.

  • Order of execution (on the server, Salesforce).
  • Type of Object Relationships Overview (Lookup, Master-Detail etc.)
  • Security Guidelines for Apex and Visualforce Development.
  • Formula fields, Roll-up summary fields Limitations, feature.
  • Ability to understand where you need to use automation or custom apex code.
  • Apex Triggers best practices. 
  • Apex Classes best practices.
  • Governor limits in salesforce.
  • When/How to use Virtual class in apex.
  • When/How to use Abstract class in apex.
  • Using the with sharing, without sharing, and inherited sharing Keywords.
  • Apex annotations. (@isTest, @future)
  • Understanding validations rules.
  • Asynchronous Apex (Batch class, Future Methods)
  • Test classes. 
  • Developer Console Basics.
  • Try/Catch block.
  • Throw custom exceptions.
  • Lightning Web components basics.
  • Minimum allowable code coverage to deploy to Production.
  • Aura Component framework.
  • Interfaces in apex.

My Tips for Passing the Exam

  1. If you are an experienced developer then you should go through sample tests and study the key topics details from trailhead.
  2. As you are going through the exam write down the topics where your answers are wrong. Then explore those areas and improve your understanding of the concepts. A great piece of advice is to use your developer org to get more hands-on experience with those topics. I find it helps to reinforce the topic if I don’t understand it completely. Then repeat this process till you get more than a 95% score.
  3. Note that some of the answers may not sound correct and you must verify those answers based on your understanding. If you are still not clear, I’d recommend joining one of the Salesforce communities and ask the question there, the community is so helpful and there are so many great people who are willing to help. 
  4. If you are a beginner then you should complete all the dev Trailhead | The fun way to learn Salesforce modules, get 1-2 years of experience, and then go through the above process.
  5. Read every question carefully in the exam. If you are not 100% sure about the correct answer don’t waste your time on the same question, check “Mark for Review” and at the end, you can review and focus on all the questions that you have marked for review.
  6. Once you are ready to submit the exam if you have enough time then cross-check all the answers once again.
