Help me educate my sister about college admissions and selection!

I’ll put up a plan for coming 4 years but I won’t bother her with it for now. Maybe I’ll just introduce her to the college concept, get into discussions to know what’s in her head for college experience, then familiarize her with the universal requirements if she’s eager. This year I’ll focus on the test preparation part and encouraging her to engage in ECs with disregard to college (introducing to HS life) Maybe I’ll let her buy Fiske’s and the majors book on her sophomore but we won’t get near to college selection this year! Hope this will work well with her and making the process interesting rather from stressful.

I found this book on Amazon, you guys tell me what you think of it?
