I’m really sorry to hear about the rejection. I know how tough that can be, especially after putting so much effort into the application process. I've been there myself more times than I can count, and I just want to say that how you're feeling now is completely valid, but also temporary. Resilience will carry you through this.
The fact that you made it to the AC stage is already such a strong indicator of your capability and potential. And the fact that you're still applying shows incredible determination. Please don’t lose sight of that.
On the case study front, you’re absolutely right to want to refine your preparation. Firms usually do offer feedback after assessment centres, either via email or a call. If you haven’t received anything yet, it might be worth following up with Graduate Recruitment, although do keep in mind that responses may be slower around this time of year because of vacation schemes.
In terms of prep, the structure and focus of a case study can vary, but there are definitely recurring themes. For example, M&A is a common one and typically involves questions around structuring an acquisition in a commercially efficient way. You might be expected to identify commercial risks, explain whether a deal should be structured as an asset or share purchase, or distinguish between a warranty and an indemnity and advise when each should be used.
No firm will expect you to master every possible type of case study. That would be unrealistic. But being familiar with the most common formats, especially in line with the firm’s dominant practice areas such as corporate, will definitely help. Also commercial awareness and keeping up on trends will help in applying issues to whatever case study you are given.
You’re also absolutely right that not having done a UK LLB isn’t a disadvantage. The fundamental skills like legal analysis, commercial reasoning, and structuring arguments are transferable. It might help to get familiar with a few UK-specific legal nuances such as contract or company law basics, but it's not a prerequisite to succeed.
If you’re looking for more practice, I highly recommend the M&A course on TCLA. LINK HERE:

Mahesh also walks through various case studies in the videos, which can be incredibly helpful to see the thought process in action.
You’re clearly on the right track. Keep going, and feel free to message us if you’d ever like to prep together or chat through any of this.
