Hi there,
I can't really comment on how lenient Leicester is on results day with grades for entry, but what I can say is try not to panic - even though it's definitely easier said than done! There is nothing you can do or find out now until results day, as I think whether they would still offer you the place will be dependent on how many other applicants meet their offers.
Usually, universities will tend to give more people offers than the course capacity. This is because they know a lot of people will put them as insurance and go to their firm, some may not firm or insure that uni at all, and others will firm and then miss their offer.
It would completely depend on how many people get the grades to meet their offer for the specific course - the admissions team would usually then re-assess and decide whether or not to take those who only missed out by a small amount.
This would all be done between the time the universities receive everyone's grades and then results day, but they would not be able to tell you anything until results day.
Obviously I am not telling you that you would definitely get accepted with lower than entry, but usually if there are still places left then they will be lenient if you are only a grade lower - if not, they may offer an alternate course such as a foundation degree in the same course you have applied for (if they offer them).
Hopefully that makes sense - best of luck!
