When will track update?Between 6-8am. Emails will be sent in waves starting at 8:10am.
When are grade boundaries released?OCR and Edexcel: 12am Wednesday - 12am Thursday (Likely they'll be out when you wake up, so just sleep
)
AQA: Wednesday (Again, after midnight though, but when you've woken up)
CCEA+WJEC: Thursday (WJEC in my experience update after 8am with their raw mark conversion)
Results or Track?Depends on when your college opens, it is personal preference and entirely up to you.
Will my firm accept me with A*AB when my offer is AAA?If your track says unconditional, you're in. If it says rejected, you're not. If it says conditional, phone in! (also, you can probably phone with a rejection too).
Now, A*AB is equivalent in terms of UCAS points but your university may not accept that. Chances are track will have told you anyway. Phone up if you receive these grades.
