Hello,

JEE Main (Paper 1 for B.E./B.Tech) has:

Total Questions & Marks

• Total questions: 90 (students need to attempt 75)

• Total marks: 300

Subject-wise (Physics, Chemistry, Maths):

• Each subject: 30 questions (20 MCQs + 10 Numerical, attempt any 5 numericals)

• Questions to attempt per subject: 25

• Marks per subject: 100

So, Physics = 100 marks, Chemistry = 100 marks, Mathematics = 100 marks.
Total = 300 marks.

Hope it helps !

JEE Main has 90 questions in total (30 each from Physics, Chemistry, and Math), but you only need to attempt 75 questions (25 per subject). Each question carries 4 marks, so the total marks are 300. Subject-wise: Physics – 100 marks (25 Qs), Chemistry – 100 marks (25 Qs), Math – 100 marks (25 Qs).
