No worries, glad I could help!
Read the student's cues and you will know when they're having trouble and need help, don't wait for them to say 'I don't know...' or 'I have no idea...' because this lowers their confidence, jump in and take the first step to helping them. You don't want to give them too much work to do during the lesson, usually lessons go for only 1 hour so you don't want to waste time on things they could just do at home. Obviously let them do a few things here and there, but also go through questions together step by step. When I tutor English, for example, I sometimes get students to write a 5 minute introduction since this is what's necessary in the exam, but I never get them to write a full essay or full body paragraph (trust me, I've seen plenty of tutors make students do this). Students/parents aren't paying you to 'watch' them do work, you should help and provide inspiration and advice.
Also I get the impression that the parents seem like control freaks - try to get in more contact with the student when you start lessons, encourage them to ask you questions etc. Try to avoid having parents as students' mouthpieces, because often the parents are forcing things onto their kids etc. You want to build a strong relationship with every student, be personable and be as approachable as possible. Crack a few jokes, talk about non-school related things at the end of each class, ask them how they're going with year 12 overall, offer them general advice, talk to them over fb etc. You want to be half friend/half mentor. Obviously don't be TOO friendly because students will not take you as seriously, and you want to maintain some professionalism as well.
