Question for who passed Plab this year


Question for who passed Plab this year.
I am aiming for Plab 1 2020 march.
I am confused how to start the preparation.My query may sound weird but please bear with me.Thank You.
I just bought my Plabable sub.
I want to know how to study with samson notes and Plabable.
Firstly-Should i read notes first and then attempt Plabable or read question from Plabable and refer to notes?
Secondly-If I read question and refer the notes , then should i read whole system as well or stick to the questions answer only??
Thirdly-if I will just stick to the answers only,then it means I am going through the whole topic!!
