LWF4 (Eng) 2011 vs F4 (Eng) 2015

It is substantially the same. There have been changes but I can't remember going backwards 4 years what the changes have been! I suggest you look at the 2015 syllabus and compare it with the 2011 study text index. Note any new bits in 2015 syllabus and check them out in a borrowed text Or........ you could always read the course notes, watch and listen to the recorded lectures, and practice, practice and practice mcqs and mtqs from a reputable revision kit But don't mark your guesses in the revision kit itself!
