Inorganic is by far the most important topic in whole chemistry for competitive exams. There will has been question from this topic and they are expected this year too. Past year trends show that 5-6 questions have been asked constantly every year from this topic. The number may go slightly up and down depending on the year but I do not think that paper setters will completely ignore this topic. From my own personal experience, I can say that NCERT and previous year question papers are enough for this.
