Not 100% sure on this but I don't think you can sit S3 without sitting S2 (I don't think you will get a full qualification if you try skipping applied units like this)

In my view, the S3 content is more challenging than S2 for a start, but the hypothesis testing and expectation and distributions in S3 come from S2 so you would have to learn S2 anyway.

Ah I see, my advice would be to just start S2 now and go through it, whilst making sure that C3 gets enough time also. Will help you with S3 and then the time where you are taught S2 can be used for revision
