What it is
The Blind 75 became the default interview practice list because it is short enough to finish and broad enough to matter. This version adds what the raw list lacks, which is the pattern label on each problem, so finishing it leaves you with transferable structure rather than seventy five memorised answers.
Why it is still worth doing
Lists like this are criticised for encouraging memorisation, and that criticism is fair when the list is used alone. Used as a diagnostic after pattern work, it is excellent: the problems you cannot start are a precise map of what you skipped.
How to use it
Do not start here if you are new. Learn the patterns first, then use this as your assessment. Anything you cannot solve in forty minutes goes on a revision list.
Best for: a checkpoint partway through preparation, or a final revision pass.

Stuck on something specific?
Writing only gets you so far. If you want an answer to your situation rather than the general case, book a session and we will work through it together. Every session is free; a few slots open each week.
