Are savemyexams notes enough for IGCSE Physics 0625, Bio 0610 and Chem 0620?

Hey everyone, I'm giving my exams of these subjects in May/June. I have previously studied most of these subjects by the book and savemyexams notes both. I was wondering if revising these subjects with only savemyexams notes with some reference to the book would be enough to score A* in all of these 3 subjects

Thanks
