  • Hi, could you please help me with physics, I have my A2 exam tomorrow. I have always written my answers to the least significant figures of the data used to calculate the answer, however after going through past papers the answers s.f vary from 2 to 3 and sometimes they write it as 3 even though data with only 2 s.f was used. Do you know what is acceptable and when? Thanks
