Hello Movies Counter. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

No, there is no change in difficulty nor a change in syllabus that has been brought about in the JEE Mains paper. 

The announcement was regarding that every section of PCM will have an equal number of easy, medium and hard questions. So, nothing to worry. 

Please continue preparing for JEE Mains by practice and solving past year question papers of JEE Mains itself. This is the most important exam to get admission into most reputed engineering colleges except BITS and the IITs. So, please study with full dedication.

Hope this helps you and all the best!
