if jee questions can repeat from previous 10 years question papers it can satisfied for jee exam.

There are very less chances that questions can be repeated as this is bit difficult so I would suggest you to complete last 10 years sample papers but as a reference of important questions only. Apart from this, you can practice on online mock papers as well as this will make you familiar with the test pattern along with this, you will be learning time management skills during exam as well.

Hope this helps!!!!

It is unlikely that the questions will be repeated from the past years. They may be same type of questions but I have my apprehension if questions will be repeated from the past JEE question papers. However, I would suggest that you solve past years question papers. This will give you an idea about the kind of questions  that will be asked, which are the topics from which more questions will be asked and which are the ones from which less will be asked.

Jee questions will not repeat,there are very less chances of repeating the questions,but you should solve previous year questions to prepare for the jee test.
