How to Use This Vault

The correct study loop

Use the same loop for every topic:

Read the short concept note.
Read the method or formula sheet.
Solve five to ten questions without notes.
Mark each answer as Correct, Wrong, Guessed, or Too Slow.
Write the reason for every Wrong, Guessed, or Too Slow answer in [[10_Templates/Error_Log|Error log]].
Re-solve those exact patterns after two hours and again before sleeping.

This is more effective in two days than reading a large textbook passively.

How to take a timed section

Use a visible timer and do not pause.

First pass: solve only questions that become clear in roughly 30–45 seconds.
Mark-and-move: if the method is unclear, mark it and leave it.
Second pass: solve marked questions with remaining time.
Final 90 seconds: check bubbling/selection and arithmetic signs. Do not reopen a question already solved unless you can name a specific reason it may be wrong.

What "PYQ" means in this vault

Question banks on the internet are incomplete, may be old, and may belong to different employers using the same platform. The vault therefore separates:

reported public question themes;
reliable skills repeatedly tested;
original PYQ-style drills that train those skills.

That avoids wasting time memorising a leaked or outdated question while still using the research intelligently.

Link legend

Formula: quick recall facts and equations.
Method: a repeatable solving process.
Drill: short practice questions.
Mock: a full timed simulation.
PYQ pattern: a topic reported in a public source, not a promise that the exact question will repeat.
