Need a quick reality check

I'm considering KCL econ as my safety choice. I take IB and my current predicted score is 6,7,7,7,7,7 with the 6 in maths (equivalent to AA*A*). I am however almost certain that my next predicted grade will be all 7s (equivalent to A*A*A*)

KCL econ requires a total of 38/45 in ib (the extra +3 is basically like an EPQ) with a 6 minimum in maths. As of now I have 44/45 but am confident it will go up to 45/45.

I consider Kings a safety option that will almost certainly give me an offer but was wondering if I'm being overconfident. I'm not studying in the UK so my teachers don't really have a good sense of the scores each course accepts.

I'm thinking regardless of whether I get 44 or 45, I'll get a conditional. Am I right to think that?
