Hello Aspirant,

See the questions of JEE-Main or such national level entrance examination are highly unpredictable because few question might get repeated but most of them would be the newer one but yes the syllabus remains same so we can guide you with the syllabus. And as of now the latest syllabus for JEE-Main 2022 has not been released but it usually remains the same so to give you an idea I am mentioning down the JEE-Main 2021 syllabus :-
