I thought the point of making the exams later was to make it harder, which really doesn't seem fair if I'll get lower grades than the year before me. Results (at least for GCSE, I don't remember the A level ones since I'm in year 12 so kinda new to this) dropped the last two years for the first time ever, so I suspect in general they're trying to make them harder or something.
I was quite bad at January exams in GCSE though (like, an exam only after like 3 months of learning the content, it seemed ridiculous) and had to resit one of the sciences, then when it came to the June exams at the end of year 11 for sciences I did really well, I guess because I had more practice and everything. So, in a way, I'm happy with the January exams being scrapped, however I do fear that people will do badly here because it's their first try, and then have to resit in June next year with all the A2 exams D:
