-I only wrote what I knew, I skipped questions where I didn't know the answer.
-If I know 10-40%, I only wrote that much without bothering about reaching the 100% answer length by writing "stories".
-Don't write vague answers that remotely resemble to what is being asked in the question.
-I write in bullet points for both general studies and optional papers in mains.
-I underline the keywords but I don't use colored pens like most girls do, I don't understand how do you hold so many pens in your hands without sacrificing speed and efficiency.
-I don't have time to write introduction or conclusion.
-Good if you write diagrams, especially for geography questions and GS3.
-Do read the question again and again while writing the answer to ensure you're not drifting away from what is being asked.
-Language matters but don't write complicated sentences, do better that "medium". Don't write Shakespeare thing. I tried previous time but didn't work."
