For this test I recommend studying for at least 4 weeks. Using the first 15 days take the free official AWS course 1 hour daily, during the remaining 15 days take 1 of our 20-question Solutions Architect Associate Study Mode Assessment complete it then save it and check your progress on the "My Track" section, do this daily. After you complete all the simulator questions do an "All My Incorrect Questions" test. Once Your track is complete (My Track - Overall score > 80%) take the final exam readiness test by doing an Exam mode Assessment (you can get a pdf certificate!), once you pass this exam you will be ready to take the official aws certification exam.

Some additional tips:
The exam is somewhat biased to use Amazon homegrown products: example always pick Aurora instead of RDS, among other things, also I noted that homegrown AWS services have some of the most popular components enhancements built-in, like caching in dynamoDB DAX vs having to configure ElastiCache for a vanilla RDS so it is worth reviewing the advantages of each one.
My thoughts right after taking this exam:
Yesterday morning I passed the test. I studied for 4 weeks starting May 1st. The first 15 days followed the acloud.guru guide for 1 hour daily, the remaining 15 days did multiple free mock tests.
Good luck!
