Chances for LSE Economic and economic history

Looking at UCAS Historical Grades, it looked like LSE accepted students in recent years with AAB and your other choices accepted students with ABB and even BBB. Although these are achieved grades of students on the course, they still give an indicator of likelihood of on offer. It looks like you have a balanced list but might want to add in one choice with lower entrance requirements.
(Historical grades are on the bottom of each UCAS course page but I used my Uniplan.me website to look up the courses in one go.)
