Year 12 mocks

Hi, Im a year 12 student and mocks in June from the 21st. I'm hoping to achieve at least 2A's and an A* so i can apply to king's college London to study law!
I have had 2 recent mocks where i achieved all A and A*'s in history, English literature and Biology so I think I'm on the right track. I had a B in crime literature which i got to an A in the second mock by the way.
If possible, could anyone give me advice on when to start studying, how to study for each subject best for good grades and ways to stay motivated as I'm finding it difficult lately.
And any other guidance would be helpful like someone's study routine

Thank you in advance for your help!

Hi! I’m a kings law applicant who is predicted 3 A*s & also takes English. In terms of English revision, essay plans are my holy grail!!! do as many past paper essays plans as possible and when you’ve run out of those make ur own based on the key themes; I promise it will help. I was on a low A from the start of y12 to the middle of it and i def owe my jump to an A* (a confident one at that, I rarely get below 23/25 on essays now) to essay plans. Best of luck!
