Is there any important question, topic for 2017 MATHS ICSE X Board exams.

Dear student, from every chapter you will have questions appearing in your board paper. 

Study the unit, Commercial Mathematics thoroughly. Make a list of all the formulae in this unit. It would be helpful.

Also, study circle and trigonometry well, cause you can expect at least two questions from these chapters.

In statistics, questions such as finding the mean, median or mode are important. You can usually get 1 question of that type.

Practise contructions since you will get a question surely from that chapter.

A page from Savings account type questions are very important.

The topic Remainder theorem is also very important. Questions are usually asked from this topic.

Now it is difficult to list all the important questions here. But I would suggest you practise previous years papers (at least 5 years) to achieve a good score. Good luck!!
