I'm taking Edexcel iGCSE maths, further maths, and physics and was wondering if I'm allowed to use a ti-84 calculator for my iGCSE exams. Thanks in advance
You are permitted to use it in Edexcel IGCSE and IAL. [It does not have CAS capabilities that are prohibited in Edexcel exams] You need to know how to put it into test mode, I recommend you also let your exam admin know you intend to use one so there is no confusion or conflict on exam day. (you cannot use a graphical calculator in any Cambridge IGCSE or IAL exams)
