JEE Main 2019 will have questions from Physics, Chemistry, and Mathematics with equal weight to all subjects. 30 questions from each subject will be asked making the total number of questions to be 90. Candidates will have to mark the correct response for each question out of four given responses.

The exam will be for 3 hours in duration. Each question will be allotted 4 marks. The question paper will be of total 360 marks. Each correct question will fetch 4 marks. Every wrong answer will result in the deduction of one mark due to the negative marking of ¼ (one-fourth) of the total marks.

It is to be noted that starting 2019, National Testing Agency (NTA) will be conducting JEE Main twice a year – in January and April. However, there is no change in the syllabus and exam pattern. ## ALGEBRA
