Hi,

As MH-CET 2019 is of JEE level so it means  the toughness of the exam will increase or some minor changes in asking type of question or about pattern but the question will be asked as per maharashtra board texbooks standards. Generally overall PCM syllabus nearly same no major changes so no worry . You just cover whole syllabus and each topic of board textbooks so it will be better for you to score more. Also MH-CET exam is easy as it is time based exam but more important is to cover whole paper withi specified time for that speed for solving is very important. Be calm and positive do your best.

All the best!!
