Choose your pair before you start practising, then tally only those sections. - Each optional section is 22 questions, so a weak section cannot be hidden behind a strong one; the pair must both be solid. - The key lists every section, so mark only the sections you picked. ### What to extract before you move on - NAT vs MCQ miss counts. - GA topics you guessed versus knew. - A personal subject-weight table for Engineering Sciences from this sitting: XE-A Engineering Mathematics, XE-B Fluid Mechanics, XE-C Materials Science and the rest. - Every question where your answer was right but your time on it was not. **Analyst note:** Mark by the numbering in the paper you downloaded. ## How to sit GATE XE 2018 1.
