Calculators All future IB students are required to have graphic calculators  (Texas Instruments TI 83 plus), with which we work in Maths, Physics, Biology and Economics, by 16th June 2008. The School orders the calculators from abroad (140 Euro each) for all students, who fill out the required form by 9 June 2008. Students with calculators will attend the calculator training sessions between 16 and 27 June 2008.
