Whoever is trying to teach you landings after only 4 lessons needs soundly kicking!
You must have time to learn the basics first - an error we see so many times is some impatient kid trying to rush new pilots through Effects of Controls, Straight and Level, Climbing and Descending, Medium Turns, Descending 2 and Stalling without having ensured that the new pilot has grasped the essentials.....
PPL flying isn't hard if it's taught properly!
