What is the lowest and Highest mark you attain in your school examination

It has been a very long time since I was in school. I made good grades in all of my classes accept for Geometry. I never could figure it out. I made mostly A's and B's in all of my other classes.

My lowest is 49 out of 100 in maths and the highest is 100 in science and english.

[b]i am not really good in Mathematics, i don't know why? my sister majored in Mathematics in college, my father also is good in numbers, my brother had satisfactory grades also, and my mom is a commerce graduate. all of them, i know didn't had a great deal studying Mathematics. i don't know why i am left alone? i study much harder than my brother but still i only get fair marks during examinations. i wont mention what my grade is LOL. but when it comes to the English subject, sociology and computer subject i most of the time had 5 mistakes in all of my exams. that is probably my strong points.[/b]

my lowest is 48 out of 100 in sst and highest is 100 in maths
