Documents attestation

So I had a question about ibcc attestaion. So the thing is that Fbise doesn't issue seperate offical marksheets for fsc part 1, so I don't have any official document for that and my 2nd year result is probably gonna come out in late Aug like at the end.

Like for the ibcc attestaion they only attest original documents I don't think they attest the portal print out so what should I do, should I get my matric certificate attested which I have rn for the time being and submit that to nust on orientation and then submit my hsc part and 1 marksheet when I get it later on. Or don't submit either, and when I get my hssc part 2, one them submit them both later on.

I'm asking bc ppl say that if you don't have your final hssc narksheet yet, you should provide the first year's marksheet, but in my case I can't provide that is that gonna be an issue?
