I did no see anybody talk about AWS certificates in Coderanch forums. Since I've seen many Java developers take this exam and probably many more are willing to take this exam, I think my giving talking about my experience may help or probably inspire others.
About me: I'm an Oracle certified Java 11 Programmer (I talked about my experience here: (https://coderanch.com/t/737860/certification/Exam-Feedback) and I'm also a Microsoft Certified Azure Developer (don't ask me why). As a software engineer I have around 2 years of experience working on AWS (using mainly Java). After I passed my 1Z0-819 exam, I decided to finally start working on my AWS Developer certificate.
As a learning guide I've used mainly Stephane Maarek's Udemy course, which is fantastic. I liked how the course was organized. There were focus on some potential obscure questions which may come up in the exam (example: how to login from the command line into ECR and push a docker image using both v1 and v2 versions of AWS CLI). Since this was a video course I decided to take my own notes (even if Stephane provides his notes as a downloadable content). I felt taking notes helped me memorize stuff more easily.
I also had access to the AWS Certified Developer Official Study Guide (https://www.amazon.com/Certified-Developer-Official-Study-Guide/dp/1119508193) book from Sybex. While this book may be great for a lot of people, I found it to be all over the place. Since it has a bunch of authors, the style of how the material is explained if different from going from one chapter to another.
For practice tests I bough the one from tutorialsdojo. They are widely acclaimed around the internet, and I must admit, they are pretty good. I also bought the practice tests from whizlabs, which were OK, although I have mixed feelings about buying from them.
The exam itself luckily did not provide any surprises. It has 65 questions, the majority being single choice from 4 potential answers, but it also has some questions with multiple choice answers. The time to complete these questions is 140 minutes with the possibility to request 30 minutes extra for non English speakers. The passing score is around 720 points from 1000. I went through all the questions in 30 minutes flagging probably half of them, and I spent an extra 30 minutes by coming back to the ones flagged. In total I finished in an hour, so there was no time pressure. I got a score of 947, which is ok, I guess...
As an exam tip which worked for better than expected is to read the question and just try to exclude wrong answers. Usually we are able to exclude 2 choices from the potential 4, which puts us in a pretty good position to be able to answer correctly. During the exam the questions and answers seemed straight-forward, I didn't really felt that the somebody was trying to trick me (like in case of OCP exam).
I hope these thoughts may help or at least motivate others.
