The most effective way to avoid negative marking is to be well-prepared. Study and understand the concepts thoroughly so that you can confidently answer questions correctly.
Regular practice through mock tests and previous years' question papers helps you become familiar with the type of questions asked and improves your accuracy.
Manage your time wisely during the exam. If you're unsure about an answer, don't spend too much time on it. Move on to easier questions and return to the difficult ones if time allows.
Start by attempting questions you are confident about. This will help you accumulate positive marks without risking negative marking.
If you're uncertain about an answer, try to eliminate obviously wrong options. This increases your chances of guessing correctly if you decide to take a calculated risk.
If you must guess, make an educated guess based on your knowledge and reasoning. Avoid random guessing, as it's more likely to lead to negative marking.
For questions you're unsure about, use logic and the process of elimination to narrow down your options. This increases your chances of making an informed guess.
Guessing without any basis is risky and likely to result in negative marking. Only guess if you can eliminate at least one or two options.
If you're unsure about an answer, mark it for review and come back to it later if time permits. This can help you avoid hasty decisions.
