Which of the following statement best demonstrates an attitude of self efficacy when it comes to math?

a I don't let calculus get me depressed because I'll never use it after I graduate.

b I had problems with geometry, so I'll have to work a lot harder in trigonometry.

c I don't need to worry about fractions and percentages because I have a calculator.

d I wasn't very good at multiplication and division, so there's no way I'll understand algebra.

I had problems with geometry, so I'll have to work a lot harder in trigonometry. demonstrates an attitude of self efficacy when it comes to math because he knows that he struggled in geometry so he need to exert more effort in higher math like trigonometry.
