I completed by CSA exam with 83%. I was preparing using linux academy and could guru courses. Whizlabs practice exams helped me to find the points where I am lagging and revisit those areas.
I have some points that whizlabs can think about.
Including questions on AWS resources like Lambda, API gateway, ECS, EMR.
There were couple of questions(3 to 6 nos. approx) repeated in the practice papers, that can be checked. As a mock examination, the repetitive questions will be wrong guiding.
Instead of just showing the marks score, can we represent the marks in terms on blue print categories. Like how we see in the actual examination. This would help people to identify the topics to be revisited.
