Should I apply to LUMS for MBA? Please help. Thanks!

I got 3As, 4Bs and 1C in O Level. Then I got 2Ds and 1C in A Level so I took one of the A Level exams again and my grade improved but went only from a D to a C. After that, I completed BBA and MBA from LSE (Lahore). My CGPA was 3.2 out of 4 in BBA and 3.63 out of 4 in MBA. I have worked as a TA at LSE for 2 semesters after MBA and have completed a 5-week internship at Coca Cola Beverages Pakistan Limited.
Considering my record, do you think I should apply to LUMS for another MBA or will it wasting of time? Because I know my academic record is not good and I have not achieved anything extraordinary. Just wanted others’ opinions.

Why would you get another identical degree? I can see no advantage to that.
