Hello

Which board are you from?

You have not mentioned the board you belong to, so I'm guessing that you are from CBSE board if you are from some other board then do let me know in comment section

You can get class 10th CBSE board new updated reduced syllabus for the session 2020 -2021 by visiting the official page of CBSE the link for the same is provided below:-

http://cbseacademic.nic.in/Revisedcurriculum_2021.html

This  syllabus  will  be  very  helpful  in  your  preparation  because  it  will  let  you know  the  topics  and  chapters which are included  in  your  examination   , so go well  through  your  syllabus  and  plan your  studies  so  that  you  can  score  well in  your  board  examination.

And yes ,  try  to  complete  your  whole syllabus at  least a   month before of your 10th board   examination   so that you can give your  last one  month for  practicing mock test  papers and  revision .

Thank you
