Executive Functioning help

Hi Everyone and Happy Weekend!

For those working with students that are doing SAT Prep, is there a prep book or online system you have really liked or found supportive for a student with Executive Functioning challenges? I see a 10th grade student who is looking to take the test in December. I am looking for a resource for her that would help her self-pace and make suggestions for how much/when to practice each area. The family is not yet ready to engage with SAT prep classes or tutors. Any suggestions would be so helpful.
