## Main Question or Discussion Point

Do you like making careless mistakes in tests and exams?

Here are some careless mistakes that I've made in my most recent math test.

1) In an integration problem, there were 2 parts. We had to find a reduction formula in the first part and apply it in the second part.

Part a )

I

I

I

I

part b) I used a wrong reduction formula deduced in part a

=5 marks disappeared

2) 0/(1+1) = 0/1 = 1 mark was lost

3) another integration problem, to integrate a rational function and I applied partial fraction.

1/(x

= 1/([x+2][x

= 1/([x+2][x

= I lost another 5 marks

more than 20% of the marks were lost due to careless mistakes !

I made lots of careless mistakes in many other tests too.

_{n}= (c-b^{2})......I

_{n}= (c-b^{2})......I

_{n}= (c+b^{2})......I

3) another integration problem, to integrate a rational function and I applied partial fraction.

1/(x

^{3}+8)= 1/([x+2][x

^{2}-2x+4])= 1/([x+2][x

^{2}+2x+4])= I lost another 5 marks

more than 20% of the marks were lost due to careless mistakes !
