How do I get my book after paying?
Straight after payment, the download link appears on your order confirmation page and in your order email. For Book 1, the same email has the password for the online missions. Book 2’s online missions are being built, and everyone who has bought it gets that password by email as soon as they are ready, at no extra cost. Print as many copies as your own family needs. Because the books are digital, sales are final, but if your file doesn’t arrive or won’t open, send me a message and I’ll sort it out personally.
Which currency will I pay in?
You don’t need to choose. Prices are in rupees (₹) in India, paid by UPI, card or netbanking, and in US dollars ($) everywhere else, paid by international card. Checkout shows the right one, and you can change the currency at the bottom of any page.
Which product is right for my child?
For mental math, start with the Math Magic Missions books: Book 2 suits Grades 5 to 8 and Book 1 suits Grades 6 to 10. They’re short, playful and work with any syllabus. For coordinate geometry, start with the free Gridhaven game (Grades 5 to 8), then move on to the Pattern-First workbook (Grades 8 to 9). Not sure? The free diagnostic for Classes 8 to 10 shows where your child stands.
Will these prices go up?
Yes. The books and the workbook are at a launch price of about half their full price. Each launch price lasts for one month after that product comes out, and then it goes back to the full price shown crossed out. If you buy during the launch month, you keep everything you bought.
