C Guess quickly
D Avoid revision
Analyzing wrong answers reveals conceptual gaps and careless habits. Understanding the correct logic helps prevent repeating mistakes and steadily improves accuracy in future practice.
A good attempt strategy under negative marking is:
A Guess all options
B Skip easy questions
C Attempt without reading
D Attempt after elimination
Eliminating wrong options increases the chance of a correct answer. This reduces negative marking risk and supports smarter attempts when full certainty is not possible.
Sectional practice is useful when you need:
A Build weak section score
B Avoid any testing

D Pattern is known
If you cannot eliminate any option, guessing is purely random. With negative marking, random guesses can reduce your score, so skipping is often a safer choice.
Stress management in mocks improves by:
A Practicing full-length tests
B Avoiding all tests
C Skipping sleep always
D Studying only nights
Regular full-length mocks build exam stamina and reduce fear of time pressure. Familiarity with the pattern makes you calmer, improving performance on the actual exam day.
“Revision after test” should include:
