I read in collegeboard website that it is expected that students who are taking this test(maths 1) use graphical clculator. Does it really matters? I mean, cant we be able to solve graphical problems without a graphical calculator? And can a scientific calculator( I have ...CASIO fx 570 MS) be ok for the test? Reply from experienced friends is highly apreciated. BUT I dont mean the reply from the ones who are planning for the test is not appreciated.
