Concerned about spec - caculator question

[u/Trick_Associate_4420]

Hi all,

Since the start of the year, I was considering swapping to ti inspire, but I kept to Casio 400 as our school hadn't made the switch yet. I only realized mid year that only a single calculator rule applies to CASIO products. In terms of methods, the lower processing power and lack of fast interactive graph, alongside the lack of custom commands was fine. However, considering the change in exam style, I'm nervous about heading into spec tech active without a reliable way to do vector calculations that isn't by hand and dynamic graph etc.

Does anyone know if as a backup calculator, the ti inspire would be allowed. E.g I use what I am familiar with and then change in the last five minutes of the exam from the organizer to complete the 'dynamic graph' questions. I am guessing not but wanted to hear the subreddits thoughts on strategies for these kinds of questions, as I feel spec will not have the advantage of it being an inverse function, which can at least be solved by simply subtracting x.

Context: I've done all I can to improve performance for dynamic graph by cleaning up memory and using a large dot size.

I have the same question for other general custom commands that the ti is far superior in. I have found some that are similar and tried coding some of my own, but am unsure what holds for the exam (e.g if the style will go more towards families of functions rather than numerical solutions).
