How to Unlock Advanced Subsubjects

Understand T1 to T4 gates and plan your knowledge route.

Key points

Subsubjects are tiered so players can begin with accessible foundations before moving into advanced or niche topics.

Higher tiers may require INT growth, VIP access, global tier unlocks, subject unlocks, or direct subsubject unlocks.

The best plan is to build a reliable base, then unlock the next tier when your accuracy and resources are ready.
