Hello ,

No there is no calculator allowed in any JEE exam neither in JEE Mains nor in JEE Advance . You should read admit card properly when you get it . It is clearly mentioned that calculators, digital wrist watch and any other electronic devices are not allowed in JEE Mains or JEE Advance .

hey,

no calculated is not permitted to use in the exam , what you can do is increase your calculation speed because in examination hall you will be not allowed to  bring the calculator .

hope this helps and good luck!
