I purchased the CBK book and the Practice Tests workbook as well. Additionally I viewed the SSCP video series by Mike Chappel (Co-Author of the Test workbook) on LinkedIn Learning. There are 7 videos, one for each domain.
I took all of the domain quizzes and the two practice tests from the workbook to get comfortable with the way questions will be phrased. You have to manually score them yourself, but it gave me great insight into what domains I had to spend additional time studying.
The last tool that I used was the free Flash Cards available through ISC2 Store. These were really helpful as well. They have several different "games" you can play with the flashcards. I used the "Memory" and "Learn" sub games to help retain the material in the Books.
I'm a visual and tactile learner so the videos and the flashcards were really beneficial to me.
Side-note: I took my SSCP exam 4 days ago and passed on the first try using these tools. I took three weeks to prepare. My professional background is: 1st year Security Engineer with a B.S in IT.
Hope this helps! GOOD LUCK!
