Dear aspirant,

CET (i.e. MAH CET) does not have the provision of online calculators.

However, the exam is easier than other MBA entrance exams on the basis of difficulty levels. It is mostly based on your mental abilities and how you interpret things quickly. It is more of a test of performing in quick speed rather than difficulty levels. Majority of the Quantitative Aptitude questions are based on fundamentals of BODMAS and mathematics concepts and there are  numerous number shortcuts and tricks which are available online in order to speed up your calculations.

CAT on the other hand do provide online calculators . This is because they test you more on your abilities to solve difficult questions rather than solving calculations.

However, if you ask me personally, before you'll be writing the paper on the D-Day, you'd have practised so much that using an online calculator would no longer feel necessary, rather waste of time.

All the best.
