The JEE Main Paper I Set A conducted on 8th April 2018 was an important exam for lakhs of engineering aspirants across the country. Organised by CBSE at the time, this exam tested candidates in Physics, Chemistry, and Mathematics across 90 multiple-choice questions. Each subject had equal weightage with 30 questions carrying 4 marks each, totalling 360 marks. Negative marking was applicable for incorrect answers, which made accuracy just as important as speed.

I decided to write this article because students preparing for the upcoming JEE exams always benefit from solving actual past year question papers. Set A from 2018 is particularly useful as it followed a balanced and moderately difficult format. Going through this paper will help aspirants understand the type of questions asked, the distribution of topics, and the level of conceptual clarity expected by the examiners. Solving such papers also builds confidence, improves time management, and highlights common mistakes that students make under pressure. I’ve included key analysis and the direct PDF download link to make things easier for serious aspirants looking to strengthen their preparation.
