Quick picks

What to check before you buy

• Your exam rules first. Many university and board exams allow only non-programmable calculators, and some entrance exams allow none at all. Check your exam notice or ask your college before buying.
• The maths you need. Engineering students usually need matrices, complex numbers and equation solving. School students rarely do.
• Natural display. Shows fractions, roots and powers the way your textbook writes them, which makes checking answers easier.
• Power. Solar plus battery lasts longer and is safer during a long exam.
• A genuine piece. Copies of popular Casio models are sold online. Buy from the brand store or a well-rated seller, and check the seller name on the product page.
