the unqualified being taught by the equally unqualified will simply mean that acquired bad habits will have to be eradicated by a proper instructor at some future juncture.
That of course depends on whether the "proper" instructor is any good or not. I've flown with some awful examples who couldn't teach IF if their life depended on it, despite their being qualified to do so. I'm talking about a basic scan and how to drive the nav kit properly, nothing complicated.
