Calculator requirements at the different levels
Middle School: Basic scientific calculator required (e.g. Casio FX83GT)
Upper School: Above sufficient but recommendation of Casio FX991ES or Casio FX991EX
Sixth Form: TINspire CX graphical display calculator (GDC) is required in the majority of cases.
For single mathematicians, the Casio FX991EX and TI30X Pro provide the minimum required
functionality for Alevel Maths but use of these calculators will not be supported in lessons.

International Baccalaureate 
A Level 
You will deselect these four options, which are allowed by the IB and therefore should not be disabled.

Deselect all of the options as nothing should be disabled  it's all allowed!!!
Ctrl+A allows you to select and deselect things. 
UPDATE YOUR GDC
If you do not have Version 4.4 then you're missing out...
To check the version of your GDC, on the homepage go to ‘Settings’ > ’Status’.
If the Version is earlier than 4.4…. you may not have access to relation sketching and the invbinom function. To update your TINSpire, first download this file and save it somewhere that you can find easily. 1. Connect your handheld to your computer using one of the long USB cables 2. Open up the TINspire 'Student software’ provided in the GDC box when you were given the calculator, or download the free ‘Computer Link Software’ from here. 3. When the handheld is connected go to ‘Tools’ > ’Install Handheld/Lab cradle OS’ and select the file from your documents. 4. Enjoy your rejuvenated, state of the art GDC! 
Skills worksheets for the GDC in Alevel and IB
