first of all dear friend!
please share your full profile!
and in all honesty 51% is too low!
a high score in IELTS( 7+) will only give your profile a little boost!
but if you scored low because of some genuine family, health or some other problems provide proofs
moreover
if you are seriously gonna apply you need to have a very strong SOP!
(my answer will probably be unsatisfactory , so wait for the reply of senior members!)
and if you want some preparatory tips of IELTS i'm an IELTS 8.5 academic scorer!
and have published articles related to IELTS tips and tricks!
