I passed last week and I have never used the fifth gear in any of my lessons. I struggled with clutch control as well and gear shifting at the first 10 lessons tbh. I found learning in a diesel is def more forgiving though than a petrol. It takes longer to learn in a petrol and master it. I learned all my manvrs apart from the bay park in my first 10 lessons. By lesson 15 I had done the bay park wasn't good at it and still I am not but I can do it. The first 10 were difficult for me but after that it got progressively easier, I passed in 22 lessons. I would give this advice to pretty much all drivers who want to pass as quickly as they possibly can, LEARN IN A DIESEL. Once you pass you can learn how to drive a petrol, it won't take you long either since you know how everything works pretty much. What I did at traffic lights was slow down a bit depending on the situation, clutch down and change into what gear was needed. take it to 2 then adjusted it to one or if I had to slow down quickly I would change to 1 and skip 2.
By lesson 15 I was just perfecting my driving really and understanding the road a bit better through anticipating/planning a bit better on what to do....judgement basically. Mechanically I could operate the car well enough but when it came to the things which involved me using initiative I wasn't ready. Around lesson 18 on wards I was on point, my 20th lesson was my best lesson and lesson 21/22 (if you count the lesson on the day) were pretty crap..well lesson 21 was awful, lesson 22 I drove well until there was a car that I should have given way to that I didn't and my instructor had to slam on the breaks and give me an earful. This was on the test day as well, 15 minutes before the test. He also showed me how to do an emergency stop like 5 minutes before the test lol for the first time.
