How about starting with your own post?
I am very weak in English and am having a final exam for Class 8 of about 100 questions. I don't know what to do. I need to improve my skills in tenses, parts of speech, active and passive verbs, direct and indirect subjects, definite articles, figures of speech, and prepositions. I also need to review all the work from previous classes.
I kindly request you to suggest some tips or give me a test paper so that I can practice. You can even refer me to one good website for studying or give me a brief explanation about the topics which I have mentioned above.
