Very happy with test simulator. I would say first prepare basic stuff around targetted course and check your preparation using whizlabs practice exams. I followed same approach for aws and gcp exams and really happy with content provided here. Question and references links are really useful.
Most of the questions are from this in the real exam. I managed to pass it with this dumps.

Very useful material, the questions were very similar to tha actual exam. The explanations provided for each question help understand the topics in question.
Excellent and professional.

It is really good idea to purchase the practice exam before you attend the exam, almost all questions are covered here. If you practice the exam you will definitely pass your final exam in your first attempt.
The practice test helped me identify my weak points and was able to focus on those areas.
I have successfully cleared exam and practice test was very helpful
I would highly recommend these practice test. It definitely validate your knowledge and gives you the actual exam like practice. The explanation for each question is an awesome feature. Highly recommended.
The Practice tests contributed a lot in passing my Aws SAA C02 exam. Thanks Whizlabs.
Hi Karthik, Are the practice exams similar to the exam? Are the exam questions harder than the practice exams?
Very good tests. The specific sections mini tests are also very helpfull..Excellent value for money. Only problem I had is that it was not very clear how many tries I had available, if there a re any limitations (which is also not very clear).
