I already know everything regarding that.
AFAIK I only can extend an ED three times based on reasons of studying - what I've done already. What's not correct in my opening statement?
I'll enroll in the advanced level if (when) I could stay here for a few months, being it under an ED or any other visa.
I'm just asking about if I acted smart or stupid by extending it on July - I mean, I'd like to know, if I wouldn't extend on July, would I be eligible for extension after amnesty? I'm asking just to make my mind up, just to blame or congrat myself.
I already have my (fare flexible to change dates) plane ticket back to EU for late October as I knew that that is the expiration date of my current permission of stay. I'm not asking "how to stay more and more" - I'm just asking if my movement in July was smart or not.
