GullyClassroom is a not-for-profit YouTube classroom run from Udumalpet, Tamil Nadu, for students who cannot afford private tuition. Most lessons are English mixed with Tamil explanations, and the language is kept dead simple on purpose.

How Gully teaches
Five ways of drawing the answer
Nothing here is a lecture read off a slide. Every subject has one shape that makes it stick, and each lesson is built around that shape first and the notes second.
Biology
Mind maps, not paragraphs
A whole chapter drawn as one branching picture, so revision the night before is looking at a map instead of re-reading a book.
History
Timelines that hold the dates
Events placed on a spine in order. Once a student can see the sequence, the dates stop being twenty unrelated numbers.
Geography
Venn diagrams for comparisons
Two things, what they share, what they do not. Most Geography questions that ask "compare" are answered from the middle of that circle.
Economics
Flowcharts for cause and effect
Sectors, credit, globalisation — drawn as arrows from one box to the next, so the chain can be rebuilt in the exam hall from memory.
Physics & Chemistry
Tough board problems, worked fully
The numericals students skip, solved on screen at full length — including the step that is usually left as "hence obviously".

Why it's free
One teacher, his family, and his old students
A. MuthuKumar teaches from Udumalpet, Tamil Nadu. The channel exists for one group of students in particular, and he says who in his own words:
Students, esp 'Namma Thamil Pasanga' who are economically poor to afford private education.
There is no company behind it and no one is paid.
The Youtube channel is managed by myself and my team (mostly my own
students, wife, sister and family) on a not for profit basis.
The teaching language is a deliberate choice, not a limitation:
Most of the video lectures will be a mix of English with Tamil Explanations.
The English stays simple because the exam is written in English and the
thinking happens in Tamil.
Board exam toolkit
For the fortnight before the paper
Everything below is part of the lessons on the channel — worked through on video, in the same simple language as the rest. There is no separate paid pack, and nothing is gated.
-
Repeated board questions
The questions that keep coming back across past papers, collected per chapter and answered.
-
Answer keys
Worked answers alongside the questions, so a student can check themselves without waiting for a class.
-
Important one-mark questions
The one-markers that decide the difference between a pass and a distinction, run through at speed.
-
Mind-map revision
The chapter mind maps rebuilt on screen in the last lessons before the exam, ready to copy into a notebook.
