CoCubes / Aon 2–3 Day Score Boost Vault

This is an Obsidian-ready vault for rapid placement assessment preparation.

Use 00_Start_Here/Dashboard.md as the home page.

What this vault covers

• Aptitude: Quant, English, Reasoning
• Technical MCQs: Data Structures, OS, Embedded Systems, DAA, Networking, SDLC, QA/testing
• Pseudocode tracing
• Coding round patterns
• Gamified assessment: planning, memory, deductive reasoning, numeracy
• Formula sheets
• PYQ-style/publicly repeated question patterns
• Timed mocks and answer keys

Important note on PYQs

Exact CoCubes/Aon question banks are proprietary and randomized. This vault therefore separates:

• PYQ-style: questions modeled from publicly repeated patterns and common placement-paper formats.
• Publicly repeated patterns: problem types reported across practice/prep sources.
• Practice mocks: original questions built to match timing and difficulty.

Use these for score improvement, not as a leaked-paper substitute.
