Choosing a guide
How do I choose the right guide?
Match four things: your class (10th, 11th or 12th), your subject, your medium of study (Tamil or English) and the edition year. Every guide on this site shows all four next to its cover.
What is the difference between Tamil Medium and English Medium guides?
They cover the same subject for the same class. The Tamil Medium guide is written in Tamil and the English Medium guide is written in English. Choose the language you write your exam in.
Which classes and subjects do you publish?
Class 12: Economics, Commerce, Accountancy and History. Class 11: Economics, Commerce and History. Class 10: Social Science and Map Practice. Each one is available in Tamil Medium and English Medium.
Which edition is on sale?
All guides on this site are the 2026-27 edition.
Ordering
Can a student or parent order a single copy?
Yes. Add the guide to your cart and place the order. You do not need an account, though an account lets you see your past orders.
How do I pay?
After you place the order, send it to us on WhatsApp with one tap. We reply with a payment QR. Once we confirm your payment on WhatsApp, we pack and send your books.
How much is delivery?
We confirm the delivery charge on WhatsApp before you pay, because it depends on where the parcel is going and how many books you order.
How do I check my order?
Open Track order, then enter your order number and phone number. If you have an account, your orders are also listed there.
Schools and dealers
Do you supply schools and bookshops?
Yes. Send a bulk enquiry with the classes, subjects and quantities you need. We discuss bulk pricing with you directly; it is not listed on the website.
I am a teacher. Can I see a copy before recommending it?
Send a teacher enquiry with your school and subject, and we will get in touch.
