Which course should you take?

FaangPrep has three courses. The DSA Visualizer is free; DSA Patterns and DSA 75 are one-time purchases with lifetime access, and moving up to a bigger plan later credits what you already paid.

How to choose

Not sure yet?: Start with the free DSA Visualizer. It teaches the same way the paid courses do, so it tells you whether the style suits you.
Interviewing in a few weeks?: Take DSA 75: a fixed list of 75 problems and a plan for each day.
Want to recognise problems you have never seen?: Take DSA Patterns. It covers all 18 patterns in depth rather than one problem list.
Want more than one?: The bundles and the Full Access Pass combine courses, and Full Access also includes every course published later.

Prices and a side-by-side table of every plan are on the pricing page.
