Hello @zolthar , have you complete all of the video lessons for the course and completed all of the learning activities as well? Getting as much practice as you can, and understanding the concepts behind what you've studied is the biggest and the best thing you can do to prepare for the exam. We write our own practice exams at Linux Academy and the only other practice exam I can recommend is the one available directly from AWS. If you have not passed any AWS certifications, the practice exam is $20. If you have passed an AWS certification already, there is a free voucher for a practice exam in your certification account.
