What if the first question of IPCC Paper left out

you wont be getting marks.. Dont worry, they will value the remaining answers written

When the institute mentions that the first question is compulsory, it means that, in case you donot attempt that question, you will be entitled to a maximum of 80 marks from the remaining questions. It means that when there is an option to choose questions and opt for choice, question 1 is not amongst them. If you choose to write all the remaining answers except Question 1 also, you can achieve only a maximum of 80 marks and will not be eligible for the other 20 marks. It does not mean that incase you leave the first question you wont qualify. There's no such thing. Don't worry.

Hope this helps :)

they will value the other questions answered ..there is no compulsion
