Graphical calculators absolutely ARE allowed in A-level exams (in fact they are also allowed in GCSE/IGCSE exams) so long as the memory has been reset to delete any possible programmable content (as you can write and save a lot more to the memory of these).

This is the calculator I would recommend for GCSE and IGCSE students and is essential for A-level. It can do everything the fx-85 can do, but has lots of extra tools. In particular the equation solver is super useful for GCSE and IGCSE and there are statistical functions that are absolutely essential for A-level. Although it is still very user friendly, there are a lot more menu options on the fx-991 compared to the fx-85 which makes the fx-85 a little easier as a first calculator for a younger student. It’s also double the price so if you’re buying it for a student who tends to lose things you might go for the cheaper option until they are closer to their exams. Having said all that, if you’re going to buy one calculator for school it should definitely be this one! A fixed tricycle landing gear was considered for the flight tests but was discarded as the drag was excessive. [12]The initial specification called for the B-36 carrier aircraft to be able to carry either one F-85 and one atomic bomb or three F-85s. [9] Davis, Larry and David Menard. F-84 Thunderjet in Action (Aircraft No. 61). Carrollton, Texas: Squadron/Signal Publications, 1983. ISBN 978-0-89747-147-3. Having said that, you can’d go on Wolfram Alpha in your exam and your school might not let you have your phone in class, so the ability to plot graphs in exams is a big plus (though most questions will still make you show working). If you’re doing A-level maths, especially Further Maths, you might also enjoy the process of learning how the calculator works. So I’d say there’s definitely a place for these still, but they are very expensive and are absolutely NOT required for A-level maths. But to answer my most commonly asked question about these… Smith, Richard K. "An Escort Appended... The Story of the McDonnell XF-85 Goblin." Flying Review International, Volume 22, No. 16, December 1967. On 3 December 1942, the USAAF sent out a Request for Proposals (RfP) for a diminutive piston-engined fighter. [7] By January 1944, the Air Technical Service Command refined the RfP and, in January1945, the specifications were further revised in MX-472 to specify a jet-powered aircraft. [4] Although a number of aerospace companies studied the feasibility of such aircraft, McDonnell was the only company to submit a proposal to the original 1942 request and later revised requirements. [4] The company's Model 27 proposal was completely reworked to meet the new specifications. [7] Top view of the XF-85, with the hook extended over top of the canopy
