80 hours total revision enough for year 12 mocks?

So 1 hour for each subject??

I am doing 3 a levels and in total I have planned to do a maximum of 80 hours of revision for them before my mocks in may/( maths and sciences)
This will be probably 3 hours a day. Is this enough to get As ( I’m on track for As anyway) if at least 90% of those hours are fairly efficient?

That’s plenty of time. I do four A Levels and I reckon that in Year 12 I did about 60 hours total revision for my end of years (got all As). It’s not about how many hours you do, it’s about working smartly. Good luck.

depends on what you do in those 80 hours, quality > quantity. if you organise your time and use it well you should be fine. go over weak areas first.

I mean some people wouldn't think its enough but it depends on how confident you feel with each subject and many gaps there are in your knowledge..
