OIR · Coding-Decoding

About this bundle

Why did the code that looked easy in your room take forty seconds in the hall? Late in an OIR sitting, the letters swim, the shift you spotted instantly yesterday hides behind a racing pulse, and the clock does not care. Coding-decoding rewards one thing: having seen the pattern so many times that your hand moves before your nerves do. That is what these five volumes of OIR Coding-Decoding are for. Roughly 1,400 pages of coding-decoding practice, spread across five volumes, so that the patterns which catch you when the clock is short become reflexes rather than puzzles. You work them in order, from Volume 1 onward, until the recognition is quicker than the doubt. Every volume is a separate PDF. Pay once, open Your Ebooks, and all five are there straight away, yours to keep and return to the night before the board.
