My grades are decent I think, I got a high 2:1 (67%) at undergrad for law at a RG university. I then got a merit (66%) for a master's in corporate law from another RG university and a distinction on the LPC MSc.
I did find the Capp test for
Linklaters a bit difficult and I have never passed a SJT test for a lot of firms so I do think my answers could have been inconsistent etc. Also, I don't know if you also did that assessment but there were WG-style questions at the end that were very difficult so maybe that played a part too!
