SBL

I have revised everything mostly for SBL & have practiced 3 mocks as well. But I’m struggling a bit to plan & understand what points to write, how to write etc, maybe feeling blank in some questions. Due to this im having anxiety of wheather I will be able to pass SBL. I have seen people taking less day to prepare and pass with 70+ in SBL. Am i doing something wrong? Is anyone else feeling the same?
