Long times between lessons is not the best way to learn. If you have the time and money, bite the bullet and book a week where you can fly a couple of times per day (weather permitting). You will soon master it, plus you won’t spend the first half of each lesson going over what you did in the previous one.
If you think that you are being given conflicting advice between different instructors, bring them together and discuss it with them. They are there to help you.
