ES and MS can bring in la. I am from last year's batch and i used it for add maths to get A. C.S.M, factorization, differentiation, log, statistics all also use that calculator

1st of all, bring a spare to be sure.
2nd of all, there isn't a letter sent to the SPM saying no 570 ES are allowed to be in. JUST NON PROGRAMMABLE
3rd of all, i have used it
4th of all, no one is free enough to check every calculator
5th of all, ur teacher is an idiot. just as when he says no liquid paper aren't allowed. i too used it. BOO HOO. he scares you will all these lies so u will listen to that fella. just as he tells u how important the add maths project is.

no actually u can't use liquid paper for OBJECTIVE OMR paper but some stupid teachers (like mine in seri suria hulu langat) say that CANT USE IN ANY PAPERS!

For all the homework? Lecturers don't mark your work as well so can use pencils but exams? Still pencils?

Best thing is bring the ACTUAL box with you if you are scared. Bring in the Casio or Sharp or whatever brand calculator you have and its box. Show the fellas if they question you. I love it when students get to shut those fellas' mouths.
