591Lab's Application Developer Certification Guide for gaining proficiency in ServiceNow.
With three years of experience in enterprise software and a mid-level IT developer role at Dhaka what makes ServiceNow an intriguing option for me? As the ITSM industry was exploding at $20 billion in 2025, I decided to specialize in custom app development and became a ServiceNow Certified Application Developer. The exam's breadth, including scripting, integrations, and scoped apps, was too extensive, resulting in 60 questions in 90 minutes that required 75% passing (paying $2250). During my research, I came across the "ServiceNow Application Developer Certification Study Guide" by 591Lab at [https://591lab.com/servicenow-/application-developer-5301-9121-certification-guide/]. 591Lab was launched in 2016 and has become a top choice for IT certification preparation, making it my go-to resource for all things IT.
The guide is a comprehensive powerhouse, starting with the eligibility criteria, which include six months of practical experience and completed ServiceNow Fundamentals and Scripting courses. This section focuses on the domains of application design (20%), user interface (150%), security (10%) and data management (80%). Among the features of this study plan is its step-by-step approach to 8 weeks of theory time on daily 1-2 hours (e.g: using "Script Includes", working in theory labs on Friday afternoon, and mocking during the weekends for mocks. By suggesting free resources such as ServiceNow's Developer site and Joseph Phillips' courses ($50 on Udemy), I was able to save hundreds of dollars on premium bootcamps.
In July, I began getting ready. Throughout the week, I was committed to learning design principles, building tables and forms, UI with Client Scripts, and security such as ACLs. Weeks 7 and 8, where I practiced integrations and full mocks were included. The guide's practical demonstrations, such as automating incident tickets with Business Rules, facilitated the transfer of theory to practice. I utilized the practice bundle from 591Lab, which was priced at $199 and matched the multiple-choice and personal interview questions on the exam, to achieve a score of over 85%.
In September 2025, the exam day was tough for me, but the guide's guidance on time management (1.5 minutes per question) and concentration on integrations helped me stay focused. I was 82% and passed, which is why the resource's emphasis is on practical issues. I was offered a ServiceNow developer role at my local fintech company for $105k after the certification, which was up 31% from $80k. The job brought in 25% more ticket resolution due to better app deployments and faster ticketing.
