Ok I can see your concern here.
I don't think there is anything you can do at this stage except wait for your overall module grade.
If the module assessment doesn;t require that you pass each component, then you will get a grade based on the weightings as published (which is presumably the adjusted ones).
Once you know your module grade, you could do an alternative calculation to see what you would have got if the old weightings had stood. The difference might be be insignificant in terms of impact on your degree classification.
If you think you have been unfairly affected by the weightings changes, then you might have grounds for an appeal BUT only if the changes were made without following the proper protocols.
