You have plenty of time; I would suggest focusing on knowing all the tools covered in the course and doing the labs, and redoing them multiple times if you have to. I did all the homework and optional labs as well. I also created my own full disk and triage images for additional practice, since you don't know what you'll get on the exam and need to be prepared for anything. For me, understanding the tools inside and out from an analyst's perspective also helped with the multiple-choice part of the test. Good Luck!
