The new A levels are linear qualifications. Just like other linear qualifications (e.g. GCSE Linear Math and IGCSEs) all that is automatically supplied to schools is a grade. Equally, just like other linear qualifications, there will no be UMS, just overall qualification grade boundaries which will vary with each exam season. This means that even if you do get the marks from your school, you probably won't be able to tell how well you did on individual papers compared to other people - getting 60 on both units could put you near the top on one paper and near the bottom on the other. (AQA issue indicative grade boundaries at a and c, but not all boards do.) (In case you think it will be different for these linear qualifications because you want it to be, I have checked the results software and there is nowhere for a mark to be entered and I have asked AQA and Edexcel and they confirm it.)
Schools will be able to download marks from the secure sites but this comes in a different form from each exam board and trying to collate that and then produce an accurate mail merge to provide individual results sheets for all candidates as well as everything else that has to be done in the 24 hours before results day may not be feasible. I'm grappling to come up with a workable plan for my school and this year we only have to worry about AS results. If you want to know marks you will probably have to specifically ask your school -either your teacher or exams officer, depending how your school operates.
All this is more information that used to be available years ago, but for a generation brought up on knowing details of their marks I think it's going to be a nightmare. I have raised this in several places but I don't expect much is going to change before the summer.
