Hello
Hope you have filled the application if not fill it soon. The application started on 3rd Dec and you can apply till 10 jan. CHSL is a 10+2 level exam, so english is not too hard for the students. The level of paper used to be easy to moderate. SSC do not make this tough. You have to first see the syllabus of the exam and go through all previous papers. SSC mostly asks repeated questions from previous papers. There are two section, vocabulary and grammer. First categorise the subject, they ask synonyms, antonyms, one word substitution, idioms and phrases, spelling mistake. Comprehension, Cloze test and error detection. Categorize this into two halves. You have about 3-3.5 months, try to complete Subject verb agreement which is more important. Complete theses two for two months. And in third month write more mocks as possible.
You can refer SSC kiran publications previous year papers book, Neetu Singh book, S.P. Bhakshi book, etc.hope this is helpful.
