Is there any source for class 12 science

Anupam Kumar Student Expert 21st Oct, 2019

Hey there

Your question is incomplete i guess. But still if you want to know about books for class 12 them for maths you can refer rs Aggrawal or r d Sharma. For physics Pradeep's physics and hc verma. For chemistry NCERT is good and enough but still you can read Pradeep's chemistry for boards.

Good luck


Ive failed CBSE class 12th twice (2018 and 2019), Im going to write class 12th boards in the year of 2020. Will I be eligible for JEE advanced 2020 and 2021 (after I clear Mains obviously)? Also is it necessary to give the first of two Advanced exams in the year of you are passing class 12th?

Aditi Amrendra Student Expert 30th Sep, 2019

As per JEE mains criteria, Candidates who have passed class 12 or any other equivalent exam in 2018 or 2019 or those who will be appearing in class 12 or any other equivalent examination in 2020 will be eligible to appear in JEE Main 2020. Those who have passed class 12 or equivalent examination in 2017 or before and those who will appear in 2021 or later will not be eligible to appear in JEE Main 2020. Aspirants who have appeared for their class 12 in 2017, failed in 2017 but have appeared again in 2018 and passed are not eligible for JEE Main 2020.

I hope this helps.
