I took the test this morning and after 10 hours, I got the notification of passing the exam. It was one of the most hardest exam that I ever took. 3 hours really tests your patience and endurance. Huge thanks to sub, without the guidance it would not have been easy to pass the exam.

Following was my study plan, it took approximately 2 months along with my work and family commitments.

1. Udemy Course by Frank Kane and Stephane
2. Udemy Practice Tests by Frank Kane
3. AWS Skill builder - Exam Prep Plan: AWS Certified Generative AI Developer - Professional (Paid)

My background : Java backend engineer with previous Elasticsearch Engineer experience. Doing AWS Cloud migration for Spring Boot apps. Have AI Practitioner in 2024 and Nov 2025 had Solution Architect Associate.

The process : Did the Udemy video course over a month first but did not do the Practice Tests included in the video course. Then started going over AWS Skill builder training material as a refresher. The knowledge checks are very trivial but for every Domain there is a Practice subsection, the Walkthrough questions are very valuable. It clearly shows the kind of questions to expect. I did all the Domain Practice questions. Then went back to the Practce question set included in the video course. Then did Udemy Practice tests by Frank Kane only 2 of them. 2 days before the actual exam, I did the Skill Builder Pretest (3 hrs). repeated it the day before exam once again.

My Practice test scores

• Video Course Test 1 - 85% (Very easy)
• Video Cousre Test 2 - 70%
• Kane Practice Test 1 - 78%
• Kane Practice Test 2 - 77%
• Kane Practice Test 3 - Did not finish
• Skill Builder Pretest - 67% ( 89% second attempt)

Exam experience : Skill Builder Pretest was the closest to the actual exam. Kane's Practice exam also had a similar difficulty level and it is also close to the concepts tested in the exam. I felt the actual exam harder than the Skillbuilder Pretest. There were some questions which I had no clue. It was very light on Sagemaker but very heavy on RAG concepts and Step Functions. Bedrock evaluations and Guardrails were throughout the exam. I finished just 15 minutes to spare, so exhausted that I could not review the only flagged question and submitted it.

Reflection: If I had done some hands-on, some bits of the exams would have been easy. But always scared of leaving something running and racking bills. Signing up for Skill Builder ($29) was the best decision. Glad that I passed, not sure what I would do differently if I had not passed it.

Once again, thank you for the support that I got from this sub without that I would not have achieved this.
