Also if the devs are reading this, plz get someone to teach the lessons who doesn’t pinch his nose while he talks, it drives me insane, to the point where I just mute it while I’m doing the problems and just read the text during lectures, because who wants to hear someone say in a nasally voice “and here you have the line x, yep this one right here, and now you’re going to notice that when line y is running in the same DIRECTION as line x, it’s called a parallel line.” (They don’t actually teach parallel lines, at least as far as I know, in this course, it’s just an example of how poor their teaching skill is) They teach a bunch of stuff student already know and when they get to the hard stuff they barely explain it leaving students scratching their heads and trying to figure out where in the entire curriculum they were taught how to do them ### 1/5 — Not the best for sure *2025-08-05* This math app will trick you with badly written questions and won’t even help show you what you did wrong in some equations. Also if the devs are reading this, plz get someone to teach the lessons who doesn’t pinch his nose while he talks, it drives me insane ### 1/5 — Doesn’t work says purchased email wrong *2024-09-22* Frustrating, the app doesn’t open....says purchased email or password is wrong.. ### 1/5 — Apparently you do have to pay…. *2024-06-29* Although it didn’t say that in the App Store! ### 5/5 — Fantastic program - Excellent curriculum *2024-05-17, version 4.0.884* I've used Teaching Textbooks with my own kids from Math 3 all the way up. I myself was faced with a career change later in life and needed a math refresher. Not only did my kids score well on the ACT in math, it was what I needed to help me land a new career. GREAT customer service. Go to their website for the best info, but always call if you have any questions - best service anywhere. ### 5/5 — LOVE TT *2024-01-08* All 4 of my kids LOVE TT! And I LOVE that I have parental controls but don't have to teach or correct math! My oldest is now a COLLEGE sophomore and TT math courses prepared him well for college math. ### 2/5 — Misleading About Price *2023-12-01, version 4.0.881* Just be straight forward about the cost of the program. I wasted valuable time during my preparation period, downloading and signing up, before I ever found the true cost. Just prut the cost right up front, if you please. ## Frequently asked questions about TT Pre ### What is TT Pre-Calculus?
