Purdue global efforts

Hey guys! I have read through most of the Purdue global post shared here, however, I’m not quite finding the answer I’m looking for… I’ve signed up to do my bachelors in ABA with them and it says effort is 15 to 18 hours a week per course, and I’m scheduled to do two courses… Which would add to 30 to 36 hours a week. Is this what I realistically should expect for those who have done two courses a week were you spending about five hours a day average on it? I hope this makes sense! Thank you!
