## Questions & Answers

**Q: Hi sir, may i use it for my gcse, a-level, nat.5 and highers?**
A: This is the calculator my Daughter was told to get for her A-Levels (years 12 and 13) and is the one that is used in her guide books which she said is perfectly fine for her.
Casio has however released a newer version of this but it is more expensive.
I hope this helps.
