Use mock tests to diagnose, not only to score
A full IOE mock test is most useful when it shows what to study next. Record your accuracy, time per question, skipped questions, and repeated mistakes after every attempt. A lower score is still valuable when it reveals a weak chapter early enough to fix it.
Taayari combines an exam-style timer with results and practice tools. Use the full mock for exam stamina, then move to chapterwise questions for the exact concepts that reduced your score.
A better review loop
Sort every wrong answer into one of four causes: concept gap, calculation error, misread wording, or time pressure. Relearn the concept for a gap, redo the working for a calculation error, and repeat a timed mini-set for speed problems.
Do not memorize an option letter. Write one sentence explaining why the correct option works and, where useful, why your selected option fails.
IOE sample questions with worked solutions
These examples show the answer and the reasoning. Use the same review pattern after every practice set: identify the concept, solve it, then explain why the answer is correct.

If x + y = 10 and x − y = 2, what is x?
Answer: 6
Solution: Add the equations to eliminate y: 2x = 12. Dividing both sides by 2 gives x = 6.

What is the dimensional formula of force?
Answer: MLT⁻²
Solution: Force equals mass times acceleration. Mass has dimension M and acceleration has dimension LT⁻², so force is MLT⁻².

What gas forms when zinc reacts with dilute hydrochloric acid?
Answer: Hydrogen
Solution: The reaction is Zn + 2HCl → ZnCl₂ + H₂, so hydrogen gas is released.
