My timetable was 3 months including one month fully committed (took work leave)
My study plan included plabable ; revised twice , solved 4 plabable mocks and 2 Samson mocks plus a 3 day review course by PLABABLE team
My recommendations :
Give yourself at least 3 months including 45 days fully committed for study like a closed boot camp 
Digest plabable at least twice including questions , explanations and even comments by other users.
My advice is to try to finish sections that contains more than a hundred questions in no more than 3 days and those that contains less in 1 and a half day for first time
Make your own notes and comparison tables.
Also subscribe to passmedicine and study its explanations at least once
Refer to OHCM , OHCS , patient.info and NICE guidelines when needed. If you can afford to subscribe to BMJ best practice it would be an alternative .
For ethics , study and memorize as many scenarios and sutuations as you can (even though they would make up a genuine new scenarios each exam 
)
Best of luck to our colleagues who are studying and planning to take the test in the near future
