The three PlansGakumas's three produce plans — Sense, Logic, Anomaly — plus shared Free cards: each plan's core mechanic and when to pick which.
Contest guideContest is asynchronous PvP fought with Memories. Here is what a memory is, the four-part power formula, why raw stats dominate it, and the practical way to push your score up.
H.I.F modeH.I.F is a separate Gakumas produce scenario with its own rules: no generic Legend cards, two main rounds, and a rating formula unlike normal produce. Here are the mechanics, the formula and the rank thresholds.
What Memories areA memory is the record of a finished produce run. This guide covers what a memory stores, its two uses (contest line-ups and carrying cards into a new run), how to filter memories by the skill cards you actually need, renting memories, and the deck-dilution trick.
Rank guideThe rating thresholds needed for every Gakumas produce rank from C to S5, how to read the table, and how to use the Produce Rank Calculator to work out the final-exam score you need.

Build guide by effectA build guide organized by exam scoring axis: Concentration and Good Condition (Sense), Good Impression and Motivation (Logic), Enthusiasm and stance-switching (Anomaly) — each axis with real core cards, matching P-items, and common mistakes.
Quick guide
The Gakumas wiki holds 19 in-depth articles, each one answering a single question players actually ask.How This Wiki Differs From The Rest Of The Site
The database pages (idols, skill cards, P-items...) list translated raw DATA — you look up numbers yourself. The wiki works the other way: each of these 19 articles answers 1 specific QUESTION ("where do I start", "how do the 3 plans differ", "how does the produce scoring actually work") in prose with examples, not tables of numbers.
If you're new or stuck on a specific step, the wiki is the better starting point — the database pages only help once you already know exactly what you need to look up.
