Hii!
Sorry, but your question is quite confusing. But, let me tell you that if you go for an improvement exam in English subject as per Kerala DHSC, the question paper will be on same pattern as it was before. The total marks will be same. The criteria to pass will be same. So, you just need to score well than the previous time in order to improve. Else, the best out of two marks marks will be considered. If you meant to ask something else, please feel free to do so.
Hope you understand.
Good luck!
