You're very welcome! It's relatively simple once you know what you're doing, but very tricky to get your head around it to start off with. All my students find that, so don't stress. Glad I was able to help out! :)
Dear madam, Your explanations are very understanding and very precise. You use easy vocabulary and your mood is very good. I have seen many of your videos and I learned much from you. Thank you..!! Ivan Castilla
