How many exams is igcse double science

[Summernights45]

Ds year 11 has told me that it's three exams but I would have thought for a double award there would be six exams

My dd school does this and I'm sure I read there were six, no way would she manage these so when the time is right she's choosing the single.
I will check though, are they all the same though, are there different boards for igcse

This from my dd school, it's Cambridge

It provides a more detailed and in depth study of science. The double IGCSE will give 2 IGCSE grades and is assessed using:
• a multiple choice paper - 40 marks, 1 hour, 30% of the marks;
• a written examination paper with short answers and structured questions -
120 marks, 2 hours, 50% of the marks;
• and a written alternative to the practical paper with questions on
experimental skills - 60 marks, 1 hour, 20% of the marks.

For Edexcel IGCSE double award there are three exams, each two hours long - one in Biology, one in Chemsitry and one in Physics, sat in that order.

Triple science does the same three papers, then three more, each one hour.
