Courses
Learn one thing properly,
not ten things halfway.
Structured courses with the theory written out, worked examples, practice and the placement material — in one place, in the order you actually need them.
The later lessons of every course, the full 120-lesson library, the mock test papers and the company-wise series. A pass ends on its own date — nothing auto-renews.

Start learningWhat is free, and what is not
Every tutorial, every practice problem, the compiler, the placement roadmap and the company pages are free and stay free. Courses are a separate, structured thing: the first lessons of each are free to read, and the rest come with a Pro pass.
Those free lessons are not a trailer. Each one finishes what it starts — if you read only those, you should still come away knowing the thing it promised to teach.
