mussaa, perhaps the problem is that nobody is actually grasping the meaning of those mistakes which you are pointing out, plus the people here really want you to give them a solid example of how a good expansion should be written, and that by writing an expansion not by telling them the tactics.

Infact, I also am still a bit confused about this expansion thing but am following your guidelines and will soon show a well written expansion but it will definitely be great if you explain us by solving one. (but nobody can compel you for that as we know aap ko khud kay bhi bohat kaam hongay to fight karnay kaa ya ghussa karnay ka tou simply kisi ko right hi nahi hai)

aap mistakes bilkul theek nikaal rahay hain, but the prob is aap ko meray jaisay nalaiq students ka saamna hai

best of luck for your guidance!
