I’m taking 3 papers f 5 6 7 next June 2018. Is it enough to aim on BPP RK + OP notes and lectures without using textbooks? I have 5 months from now with studying full time. What do you think?
Absolutely. But be sure to practice a lot for these papers. Lots of practice is the key and secret to passing these exams. You may also have a look at the examiners reports in the interest of time, just to have an idea how marks are allocated, how to answer questions and what are the things that make students not passing these.
