Public PYQ Patterns: Research Synthesis

Pseudocode / programming logic

The public CoCubes sample PDF contains pseudocode/output questions that exercise:

  • accumulating a loop total;
  • repeated multiplication/power;
  • loop bounds;
  • number reversal using MOD and integer division;
  • nested IF/ELSE binding;
  • Fibonacci-like update order;
  • arithmetic swapping;
  • recursive sum and factorial.

High-return conclusion

Do not spend time memorising language syntax. Spend it on [[04_Pseudocode/Dry_Run_Method|variable tables]], MOD/DIV, recursion and update order.

Technical MCQ patterns

A publicly archived CoCubes-domain page reports questions around:

  • DBMS transaction conflict serializability;
  • page faults;
  • hamming distance;
  • IPv4 subnetting/host counts;
  • channel-capacity calculation;
  • valid host address selection.

Candidate reports from CoCubes-hosted tests also mention:

  • DNS port, TCP vs UDP, HTTP methods/status;
  • quicksort worst-case complexity;
  • tree-level node count;
  • queue/FIFO;
  • binary search/divide-and-conquer;
  • linked-list loop detection;
  • SQL joins, count and transactions.

High-return conclusion

Technical questions are commonly textbook-level but time-limited. Learn the keyword-to-answer mappings, then practise a few application questions.

Coding patterns

A 2025 candidate report for a CoCubes coding assessment mentions:

  • unit digit of a power;
  • accumulating values from a collection.

Other public experiences show arrays/strings, tree properties and medium data-structure questions. That supports this priority:

  1. number logic and modulo cycles;
  2. linear scans;
  3. strings/arrays;
  4. hash maps and sorting;
  5. basic trees/graphs only after the above.

Aptitude patterns

Public CoCubes-oriented material repeatedly lists:

  • percentage, ratio/proportion, speed/time/distance;
  • grammar correction, vocabulary and reading comprehension;
  • series, coding-decoding, blood relations and statement/conclusion.

Gamified assessment

Official Aon guidance names:

  • working memory/grid challenge;
  • complex planning/motion challenge;
  • deductive reasoning/switch challenge;
  • numeracy/digit challenge.

This is why the vault gives a separate method for each ability instead of generic "play games" advice.

Revision use

Read [[03_Technical/Technical_Quick_Recall|Technical quick recall]], then solve [[07_PYQ_Research/PYQ_Derived_Drills|PYQ-derived drills]]. Repeat any error with the linked concept note.
