Help Us Improve
No book is perfect — and we'd much rather hear about a mistake from you than not at all. Every report you send goes straight to our editorial team and helps us correct the next print run, so the student who reads this book after you gets it right.
You're not just pointing out an error — you're quietly making someone else's studying a little easier. That's a genuinely good thing to do, and we're grateful for it.
If you'd like to share your email, we'll personally write back to say thank you once your report has been reviewed. No email needed if you'd rather stay anonymous — either way, your report counts.
We review every report within a few days. Once confirmed, it's added to our Corrections & Errata page so other students benefit straight away — and confirmed corrections are also queued for the book's next print run, with thanks to the readers who helped catch them.
We've received your report and really appreciate you taking the time. Reports like yours are how our books keep getting better, year after year. If you shared your email, we'll be in touch with a thank-you once it's reviewed.
