To anyone that's studying atpl airlaw?
If you really put the effort in and have read all the required documentation and you feel you're ready for the exam.
I strongly recommend to get the "Trevor Thom airlaw exam book", which consists of 3 trial exams.
If you pass these then you'll pass the real exams.
But only do the trial exams when you have completed your course of study and feel fully prepared.
Don't play with trial exams and just learn the questions and answers.
