I had practiced frcr longs , long cases prior to my exam. The cases are good and helps you how to answer in long cases as well as viva. Answers are to the point and i believe after seeing the real exam that time is short and you have to give to the point answers.
RR also gives you an idea to the cases.
Another good thing abt frcr longs is its reasonable subscription.
One suggestion would be to increase the number of long cases as i found those too useful.
