Hi all, I am in year 12 this year and I am not sure when should i try past papers. Say for example, in Chem I have done module 5, and 6 during this holidays and also started mod 7. Question is do i need to wait for module 8 to be finished or can i start past papers and answer any questions related to mod 5 and 6? Do you all use past papers for trial preparation or after trial only or throughout the year? sorry, i am confused in this area and any help is much appreciated.
