Front-end Engineer

I have gone through most of your HTML and CSS classes so i thought i might be prepared for your front-end engineer track but i have gone only a few pages in and you are already talking about more than beginner javascript and now SQL in more than beginner ways… my suggestion is… if this is intended to be an overview of what we will be learning please say that and make it more of an overview style because right now you are just scaring me away… this stuff is way over my head. Sincerely,
