How many weeks do I need to prep for the TACHS exam?

My daughter is in 7th grade and we just found out the TACHS is coming up in November. I feel like we're already behind — her older brother didn't take it so I have no idea what to expect. From what I've read, the TACHS covers Reading, Language, Math, and Abilities, but I don't know how hard the math section actually is compared to what she's doing in school right now.

We've started working through a TACHS Mathematics Practice Test this week and honestly some of the quantitative reasoning questions caught her off guard. She's a solid student, mostly 90s, but the format is really different from her regular tests. How many weeks did your kids prep, and did you use tutors or mostly self-study? I want her to feel confident walking in, not panicked.

Any advice on what to focus on first would be huge. Do the Abilities sections actually count a lot toward admission decisions? I can't find a straight answer anywhere.

Honestly the Abilities section worried me too but most admissions directors I've talked to say they look at the whole picture, not just one section. The math is where I'd put the most prep time — some of those word problems are trickier than they look. We also did tachs exam practice test sets timed, which helped my daughter get comfortable with the pacing. She said the real thing felt less stressful because she'd already practiced under pressure.

We started about 8 weeks out and that felt like the right amount of time. The tachs practice test materials really helped us figure out where the gaps were early — my son was fine on reading but the abilities section tripped him up because you can't really "study" for it the same way. What worked for us was two focused sessions per week, not cramming. He got into his first choice school so I think the approach paid off.

Eight weeks is plenty if she's consistent. Don't skip the vocabulary sections either — a lot of kids underestimate them. Even just 15 minutes of practice tachs exam questions a few nights a week adds up fast. Good luck to her!
