CSAT's Permutations and combinations is complete: fifty-one guided lessons in eleven chapters, from the counting rule to arranging, choosing, counting in pictures and chance, ending in an exam room of mixed questions.
The new lessons take smaller steps. Each idea is first done by hand, then asked again in a new setting, and only then given its name.
Every question has a picture of its own: a race podium, a tea stall, a street of houses, a bus-stop queue, a fruit bowl, a ring of friends shaking hands, a sock drawer in the dark, a bag of marbles.
More than a hundred questions from past CSAT, bank and NDA papers are in the lessons, each with the paper's own options.
The last chapter is an exam room: mixed questions in the manner of CSAT and the bank papers, and a lesson on the two-statement questions CSAT sets.
All five lessons of the first chapter are free with an account.
Polity has grown from four lessons to eighteen. Its first two chapters are complete: Before the Constitution, from the Regulating Act of 1773 to the Independence Act of 1947, and Making the Constitution, from the Constituent Assembly to the Parts and Schedules.
Each new Polity lesson is told in pictures of its own: a polling room where a wall goes up for separate electorates, a railway signal box for dyarchy, a country bus for provincial autonomy, a chest of twelve drawers for the Schedules.
The first Polity chapter ends with a lesson of mixed questions on every Act, in the formats a paper uses.
Each of the new Polity lessons leaves ten cards in your review, and all eighteen are free with an account.

The front page is new. It says what the platform is, and under it you can look through its parts one at a time: lectures, test series, guided lessons, current affairs, Chat and mentors.
The front page shows our toppers with their ranks, and what two of them wrote about their time here, beside the notes in their own handwriting.
The courses and their prices are on the front page, and the rooms stay at the side as they are everywhere else.
You can share a course, a lecture, a test series, a current affairs story, a CSAT topic, Polity or today's Wordl from its own page. On a phone it opens your phone's share sheet; on a computer you can copy the link or send it to WhatsApp, Telegram, X or email.
A link you paste into a chat now shows what it is: the name of the lecture or course, on a card of ours.
Polity says Free for now beside its name. Every lesson in it is free while the rest of the course is being built.
Polity is a new room: Indian Polity taught as guided lessons built on the institute's own notes. Each lesson tells its story in short animated films, then asks questions the way the exam does.
The first four Polity lessons are open, from the Regulating Act of 1773 to the Crown taking over in 1858. They are free with an account.
A Polity lesson you finish leaves a few quick questions behind. They come back in Review the next day, then after three days, then a week, so the facts stay with you.
Polity lessons have sound. The speaker button at the top of a lesson turns it off.
Syllabus is a new page in your account: the UPSC syllabus topic by topic, for Prelims and for Mains. Tick a topic when you have studied it.
Finishing a lecture ticks the topics it teaches, and a test you sit ticks the topics it asked. This works for LINCOLN, ACUMEN, GENE, the Answer Writing Workshop, the Xinsheng test papers and CSAT, and it counts what you finished before today.
A topic you have not gone back to for a while is listed under Revise next. Press Revised today when you have gone over it, and it stays away longer each time.
My learning shows how much of the syllabus you have ticked.
If you are on GENE, Anthropology has its own place in your Mains syllabus.
LINCOLN 2026, the Prelims cum Mains course, is on the site: 45 recorded lectures in Modern Indian History and Indian Polity, for ₹60,000 with a year's access. More classes are added as the batch is taught.
The numbered LINCOLN classes have their handouts under the lecture, to read and highlight on the page.
The History orientation and Polity Class 1 of LINCOLN 2026 are free to watch.
The LINCOLN handouts have been checked against standard references and corrected, and each now sits under the class that teaches it. A class taught in parts has its handout divided among the parts.
A lesson's page is quieter. The course's name is one line above the title, and how long a lecture or its reading runs is said once.
The chapter beside a lesson is a plain list: a tick for what you have finished and a dot for where you are. Watch, Read and Worksheet sit under the lesson you are on, and stay there while you read.
The button at the foot of a lesson says Complete and continue. It is a small button in the corner now, not a bar across the page, and on a computer it names the next chapter beside it when you are about to leave this one.
The chapter list beside a lesson is smaller and quieter, so the lecture is the main thing on the page.
On a computer the chapter list can be put away with the small button before the course's name, and stays away until you bring it back. A lecture gets the room.
On a computer and an iPad held sideways, the rooms have moved from the top of the page to a rail at the left, a picture and a name each. The button at its foot folds it down to its pictures, and it stays as you leave it.
In a lesson, a test or a game the rail is folded, so the page keeps its room.
Chat opens on the question box, in the middle of the page on a computer, with the examples under it. Your earlier chats are behind History at the top, and Mentor Connect is beside it.
On a computer, the article an answer cites opens beside the answer with its whole text. Press another article to read that one, or Read in the book to open it in the Constitution.
The site is calmer to read: page names, headings, prices and buttons are smaller and lighter, on a phone as well.
The Menu on a phone and a tablet lists the rooms the way the rail does.
The Constitution in Resources is plainer to read: the text in one column on a clean page, a few small buttons in the corners, and the contents in a panel that opens when you ask for it.
Find in the Constitution looks through the headings and the text from one box, at the top of Contents.
Text size, paper and line width are in a small panel under Aa, and line width now works on a computer too.
The line at the foot of the Constitution shows how far through the book you are. Drag its handle to go anywhere in it.
A page of the Constitution no longer scrolls inside itself, and on a phone its buttons are one row.
The Constitution's articles have been cleaned in 43 places where brackets and footnote numbers from the printed edition had been left in the text.
8 October 2026

Sign in and Create account are buttons at the top of the homepage. Once you are signed in, My learning is there instead.
The homepage lists the courses with their prices.
Pricing, Contact us and the policies can be reached from the foot of the homepage.
The daily Wordl card no longer opens over the homepage. It shows on the first page you open after it.

In CSAT, the first chapter of every topic is free to try. The rest of CSAT will be ₹8,000 for a year, and comes free with XINSHENG 2027 Complete.
In a test on an iPad held sideways, the question numbers at the side are bigger and easier to press.
At checkout in Safari, the State box is the same size as the boxes beside it.
The account picture and the small close buttons are easier to press on a touch screen.
6 October 2026
Release notes start today: what improves on the site is written down here.
A course page opens faster. It arrives already drawn instead of filling in piece by piece.
On an iPad held sideways, a lecture fits the screen: the picture and its controls stand clear of the bar at the foot. The same on a small laptop.
On an iPad, pressing a button twice quickly no longer zooms the page, in a lesson or in a test.
The Constitution ebook opens on its cover properly on an iPad and a computer, and its toolbar stays on one row.
In Safari on an iPad, an iPhone or a Mac, a course page no longer draws itself twice.
The links at the foot of a page and the small buttons in the bar are easier to press on a touch screen.

A very short lecture no longer runs out of views early.
On an older iPhone, a free lecture now tells you to sign in to play it.

The reader keeps your place when you switch to full width and back.
If a mentor is no longer available, the calls booked with them are cancelled and you are told in your Inbox.

A shared course link shows a picture.
Try again on an error page now reloads the page properly, and Night stays on after you press Back.
Smaller fixes on Saved, the Courses search box, course FAQs and Highlights.
Security and reliability fixes across accounts, payments and mentoring.
