1984全国理科高考入学题

So I discovered a copy of my Tsinghua Univ. transcript for my B.S study in 1984- 1989.  and my  高考入学 score total 550.  According to my brother,  full score for biology was only 50. ( he saved my injured self-esteem for I couldn't fathom that I only scored 44 out of 100).   The maths full mark was 110+10.  But according to what others believed, it was the most difficult exam.
