I would suggest going for BPP or Kaplan. These two are the best institutions for ACCA. However these two do provide distance learning online live classes which are as good as studying at the institute itself. Distance learning is also a great option if you have a job.
If you are looking for a cheaper option LSBF is a good one. LSBF also has distance learning option.
Best of Luck.
I would suggest definitely LSBF, very good tutors. Lectures, books and revision cards very useful (even comparing to Kaplan - had for P4, very unpractibale, not understandible, very much, but nothing answer in full). Distance learning from LSBF very good (better than Kaplan) platform also. One or two exceptions for P4 and P5 pls dont take from LSBF (current tutors are not so professional as could be, een for P4 they had very good one Taher, but it was 3-4yrs ago, now P4&P5 tutors are very bad...). Kaplan distance learning I liked very structured helpful.
