Apologies for posting it so late. I passed my AWS Certified Developer with 90%. The course was outlined perfectly especially the practice tests, which were really helpful.
Failure in these tests was my biggest success in the exam. I practiced these sections again to get better understanding and passed all the practice tests which ultimately helped me in passing the exam.
Special thanks to the instructor, Christophe. I also recommend new bees to go through AWS Essentials course first to make things easier.
