I did year 11 engineering distance ed with SDEHS. How it worked was they sent worksheets through the mail and also pdfs online, along with a textbook chapter. You needed to do one set of worksheets each week, and we arranged with our teacher to do fortnightly web lessons. The worksheets were pretty easy and was basically just copying the textbook. We also had termly study days where we’d go into the school in Woolloomooloo, and try cover a lot of content in 4 hours. Overall it was alright, but the struggle is not having someone to ask questions in person, especially cause engineering is sort of content heavy. I’d recommend utilising all email messaging systems with your teacher, and if you’re struggling and they are a nice teacher book extra one on one meetings if you feel you’re falling behind. Ig it also depends on the nature of the subject you’re doing, and the school you’re doing the distance ed with
