I take a look at SIX things students forget you can with the Casio Classwiz fx-991EX.

I think schools should dedicate more time in explaining how to properly use a scientific calculator to check one’s results, thanks for the tips!

[thalenagundersen]

The 6 things listed in the video:
1. Calculating solutions of x --- using the 'Solve =' function
2. Converting between different units -- using the 'CONV' option
3. Finding/Checking an equation of a line "y = bx + c" --- using the 'Regression Calculation' function, listed under 'Statistics'
4. Factorising polynomials
5. Generating values for a function, to find the first "n" terms of a sequence -- using the 'Table' option, under 'Menu'
6. Generating values for a function, to obtain an idea of the nature of its graph -- also using the 'Table' option

never seen a better value for money calculator than the 991ex.

This explanation is absolute amazing! Thank you very much for the tips!

[Alex-Projects]

Great stuff for before exam prep, thanks a bunch !!

[Faith-zpkf]

Thank you so much, had a question so similar to this in a mock and for some reason didn't check it using this, will definitely do so from now on!!!

Thank you very much, Jack! I'm an independent candidate whose been trying to complete the A level in 100 days in time for these exams and your videos have been a huge help. Other than past papers what would you say the best way to revise was as there aren't many past papers for the current spec. (I'm doing the Edexcel course).

You're a star jack, will be sharing with my students 😃

Nice video Jack, thank you. I especially like the "honing in" Sin x solutions, which I may be borrowing in the future. Good tips all round.

[janani]

Loved this! My teacher/class always make fun of how much I like to use the formula booklet and calculator. :)

[teabedran]

Tanks so I have a math SAT and this is just what I needed.

[tamaskovacs]

Thank you, and for your direct response to my comment too

[williamweatherall]

This is a really good video. If I could offer a tip, it would be that for conversions it is easiest to start with the number you want to convert and then press the conversion key

[AceOfHearts]

Great video Jack. Thanks.

I would personally say that it is worth getting a more powerful calculator for A-Levels. It is a bit more to get used to but the extra features can be a great help in exams (for example, checking all the solutions to a complex trigonometric equation using the graphing app).

For GCSE, the trade off in learning to use a graphic calculator is probably not worth it (some common functions become secondary shift operations etc.)

Damn I wish I saw this before edexcel paper 1 lol. Thanks a lot, it might save me in the next 2

[mrping]

this is a great video, thank you so much

[Waleed-fjhb]

extremely helpful. i only knew 1/6 before this

[kabir]

shift 8 about to me my life saver for mechanics 😂🙏
