when it becomes a habit... then try to follow this - read eng, listen eng and speak eng and dont forget to write too.
do i need to learn? or just understand the concept?
u talking abt literature or grammar...? or both?
how do u study it? like it's u understanding on ur own or being taught by someone?
being taught by some one as well as understand by myself
what class r u in?
I had completed my 12th
but scored so bad in exams
okay so... u r looking those ncerts, right?
read the chapters thoroughly.... like 3-4 times for 1st time reading... then u can watch videos explanations by apni kaksha(try ones meant for 2022 boards and other short, old summarise version for quick revision and understanding) , then again read ur textbooks and underline important points... solve ques given in chapters and refer pyqs
