One exam, then one lab
Pick one exam. A study hour is one objective from that exam, then one lab you can explain without the hint open. A second logo can wait.
One exam, not three
Write the name of the exam and stop. A stack of logos is not a plan. The certification workbench is the set of study lessons already on this site. Use those for the exam you named. Do not open a second exam outline in the same hour.
If you do not know which exam yet, that is the work of this day: choose one, and write why it matches the job you want. The careers page is six paths. This block is the one that ends in a lab you can talk through, not a list of badges.
What a study hour looks like
Read one objective. Close the book. Then sit a lab that uses that idea: a header, a logon, a packet, a policy. The first week is seven of those pages if you do not know which lab to open.
The hour is finished when you can say what failed, who could reach it, and what you would change. The findings page is that sentence. If you cannot say it, you read the objective and did not study it.
What to ignore
Ignore a second certification, a longer book, and anyone offering you the questions. Practice is a lab with a written scope, not a list of answers. If a page claims to be the exam, close it.
One exam, one objective, one lab, one note. Do that again tomorrow. The rest of the logos are a later year.
