The 2025 syllabus contains much of the same content as the 'older' syllabus, but it's reorganised. I think it is best to ask your teacher if what's covered in your current course is in the videos you're using. I know that's not ideal for you, but the videos we have made here are for the new syllabus. If you want to see the videos we have for the older syllabus, then go to app.oscstudy.com to see the Biology there. We have both the old and new syllabus covered there. :)
