Applying to KCL for competitive courses

I've emailed KCL begging them to let me in for any courses related to accounting finance or economics. I got B B B in maths economics and business. I’ve got QMUL and City St George offers but I really want KCL. Is it possible that they may give me a spot they most likely will see my email on Monday but idk if they will accept me.

Do you meet the requirements for those courses? Are any of those courses in clearing? Did you call the clearing line?

I couldn’t call today but I emailed them. I don’t meet the requirements.

Are the courses even in clearing?

No, but I'm asking if there are any spaces.

No, but I'm asking if there are any spaces.

If they aren't in clearing, they aren't recruiting. If there were spaces, they would be listed in clearing. Note you would normally still be expected to meet the standard requirements. You'd also still need to contact them through the normal manner for clearing by calling the clearing line.
As you sent an unsolicited email requesting to be considered for courses not in clearing while not meeting the requirements, I doubt your email will even be responded to during one of the busiest times for admissions. Realistically I would not expect any response, and if they do respond it will be a pro-forma one informing you the courses are full.
