what are my chances of getting into lums

Hey guys,I am currently an A2 student
I have scored 4A* 3 as and 1b in my olevels
And also 3as and 1b in AS levels.
My SATs score is 1740.
Now should I apply to lums for economics at this score or should give a retake of my SATs also my reluctance to give sats again is because I am afraid it will affect my preparation for A2 exams.
Please help really stressed out.
