good quality but not to use on exams
it is really good quality my daughter loves that she can write on the screen, but apparently she is not allowed to use it when she does her GCSE exam, not sure about other schools. overall it's really good and easy to use.

A Versatile Calculator with Clever Stylus Pad – Great for A-Level and Engineering!
Surprisingly useful calculator for A-Level, Engineering etc. The stylus-notepad is fun, useful and conveniently easy to use. The calculator is a standard scientific, broadly in line with the old workhorse Casio fx-991EX. Under the MODE menu we have: 1. COMP 2, CMPLX 3. STAT (1 variable and 2-Variable Regression of all kinds) 4. BASE-N (DEC, HEX, BIN, OCT; includes logic functions e.g. XNOR, NEG) 5. EQN (Up to cubics; others available via the SOLVE function) 6. MATRIX (Up to three 3 x 3) 7. TABLE (Single function f(x) only) 8. VECTOR (2-dim or 3-dim with dot and cross product) Good to have the functions accessible via buttons rather than deep menus. Factorial, nCr and nPr for example, are accessible using only the SHIFT key. The very useful ":" multi-statement button enables you to show a sequence of calculations with successive presses of the = button, and the ANS key adds another layer of useful recursion. Numerical differentiation and integration work fine, and there's a Sigma template for summing single-variable functions over a given range. All in all, good value for money and the folder stylus pad makes the most useful calculator cover out there.

Calculadora científica de marca asiática pero que cumple con su cometido. Trae una funda con lápiz para la pantalla para poder hacer anotaciones. Por ahora ha cumplido con su labor
