dear reemali 
dnt worry , we are here to help you out . 
frst of all let me know which part you are feared of – organic , inorganic , or physical . 
frst of all start with ncert , if exams are near , then just read some imp topics from ncert and your school notes , you cannot do more than that in limited time . 
after exam , try to strong your besics in 11^th , specially in GOC , they are vvimp in class 12^th . 
you have to do the following steps for chemistry 
1- frst read ncert textbook , ( twice at least ) 
2- go with beginners level ques from any ref books . 
3-then identify your weak area and solve ques from that topics only . 
4- in case of reactions , make a note of it , and paste it on your study room . 
5- then move to previous year paper . 
HOPE IT HELPS 
CHEERS
