What You Actually Get When You Sign Up
Teaching Textbooks is an automated tutoring system wrapped around video lessons and algorithmically generated practice problems. It was built for homeschool families, but you see it in public school intervention programs too. The core idea is simple: the software grades work automatically, tracks errors, and serves up mini-lessons for topics the student got wrong. That's it. No teacher calls home. No parent involvement required unless you want it. I ran this with my own kid last year. We hit a wall around the unit on matrices. The system would generate a practice set, she'd miss three out of five problems, and instead of routing her back to the matrix video or serving a remediation lesson, it just flagged the answer as incorrect and moved on. I spent twenty minutes digging through the help docs before realizing the issue — her account had auto-advance enabled, which bypasses the mastery loop entirely. She could earn perfect scores without actually learning anything because the system never forced her to re-attempt until she got it right. Disabled auto-advance, went back, and the whole thing clicked. Takes about five minutes to fix in Settings.
Teaching Textbooks Pre Calculus
The Pre Calculus course covers the full high school curriculum leading into calculus. You get the standard units — trigonometric functions, polar coordinates, conic sections, limits, matrices, and an introduction to derivatives. The lesson structure follows their Teach-Learn-Practice model. The Teach section is a narrated video walkthrough of the concept. Learn is the interactive lesson with embedded check-points. Practice generates unlimited problem sets with instant feedback. Each practice problem shows step-by-step solutions after you submit your answer, which is genuinely useful when you're stuck and can't ask a real person for help. Where the platform actually excels is the diagnostic placement test. Most kids who walk into pre-calculus have gaps from algebra two or trigonometry. The system tests those foundational skills first, identifies exactly which prerequisite topics are weak, and maps remediation paths directly inside the course. This saved us maybe forty hours of review compared to going through a traditional textbook chapter by chapter. Without the diagnostic, you're either boring a kid who already knows the material or losing them in the weeds while they haven't learned factoring yet. There's a quirk with the graphing utility built into the Practice section. It only supports two-dimensional Cartesian graphs in the standard interface. If a student needs to visualize a 3D vector or a complex plane, they're on their own. I used Desmos as a supplement, which worked fine but meant keeping two tabs open. Not a dealbreaker, just something to know upfront.
Getting Started
Sign up at the Teaching Textbooks website and purchase the Pre Calculus course. You'll get a student login code within about five minutes via email. Create the student profile, run the placement test, and let the system assign the starting point. If the diagnostic shows the student is ready for the full course, skip the remediation modules and go straight in. If it flags gaps, spend a few days on the prerequisite patches before moving on — the system won't let you skip them anyway unless you turn off prerequisites, which I'd recommend against. The monthly subscription runs around twenty-five dollars per student. There's no family discount on additional courses unless you're on the Homeschool Plan, which bundles access to the entire K-12 catalog for roughly eighty dollars a month. If you only need Pre Calculus, the single-course plan is the way to go.

How to Actually Make It Work
The biggest mistake I see families make is treating the videos as optional. The system presents them as optional because there's no hard gate preventing students from jumping straight to Practice. Most kids who do this end up with low mastery scores and no idea why. The videos contain the actual explanatory content. Practice reinforces it. Without the video foundation, the problems are just guessing games with math notation. Set a realistic schedule. The course is designed for a full academic year — roughly one lesson per school day, five days a week. If you're accelerating, don't exceed two lessons per day. The system doesn't cap progress, so it's easy to race through and accumulate a streak of correct answers on problems that should have taken more time to sit with. Here's something the help pages don't emphasize: the error analysis reports in the instructor dashboard are where the real value lives. They show exactly which problem types a student is missing and whether the misses cluster around a specific concept or are spread randomly. Random misses usually mean calculation errors — they need more practice. Clustered misses mean a conceptual gap — they need to re-watch the Teach video for that topic. I checked the reports weekly and it took maybe ten minutes, but it prevented us from blindly plowing through chapters the student wasn't actually absorbing.
One more practical note — if you plan to print worksheets for offline work, export them through the Print feature before you start a new Practice set. Once you submit answers, the system locks that problem set and you can't regenerate it. I wasted an afternoon trying to print a problem set after my kid had already completed it twice. Couldn't get it back. The system keeps a history log, but it's not formatted for printing. Just be aware.
Where It Falls Short
The video explanations are competent but not exceptional. A student who learns well from classroom teaching will adapt fine. A student who struggles with dense narration may find themselves pausing and rewatching segments multiple times, which the system doesn't track or optimize for. There's no transcript download either, so if your kid learns better reading along while watching, you're out of luck without third-party tools. Advanced topics like limits and derivatives get treated as introductions rather than deep dives. The course touches on them because that's the pre-calculus scope, but the depth is surface level. If your student is planning on taking AP Calculus, this course will prepare the foundation but won't give them the rigor they'd need. Supplement with a separate calculus prep resource or a dedicated AP Calculus BC course if that's the goal. The customer support response time is slow. I submitted a ticket about a grade synchronization issue between the student and parent portals and got a reply four business days later. The fix was simple — their system just needed a manual sync triggered on the backend — but the turnaround meant we worked through a weekend without access to updated scores. For most families this won't matter because the platform is designed to run without support. But when something breaks, it breaks quietly.
Overall, it does what it says it does. It automates the tutoring part of pre-calculus and handles the grading, practice generation, and progress tracking without requiring any parental subject expertise. The main risk is letting a student coast through without engaging with the instructional content. The diagnostic and error reports are your early warning system for that. Check them regularly and adjust from there.
