Should I publish my incomplete online course?

I’m an online chemistry tutor from Europe, teaching high school students daily to help them pass exams and get into college. For the past two months, I’ve been developing an online chemistry course that includes theory explanations, tasks in PDFs, and video explanations for difficult problems. I want this course to be top-notch in every way, but since I’m handling everything on my own, it’s taking a lot of time. Unfortunately, I can’t afford to hire help.

So far, I’ve completed 2 out of 12 chapters. Finishing the entire course will take me about a year. For these 2 chapters, I’ve prepared 2 hours of theory, 300 exercises in PDFs (most textbooks on the market have about 300 exercises for all 12 chapters combined), and over 10 hours of detailed video explanations. I’ve done my research, and I know that what I’ve created so far is competitive. My students love the tasks I present during our lessons.

Now, I’m considering publishing these 2 chapters on my website and charging a small fee—around $3/month for a subscription—with plans to gradually increase the price as I add more content. My goal is to eventually charge around $15/month for the full course (about 2 hours of minimum wage in my country). My strategy is to offer the best quality at the lowest price to attract a large number of students.

However, I’m concerned that students might not take me seriously and label me as the “2 chapters guy,” even if I eventually complete and publish the entire course. Is it worth publishing now, or could this be a false start? I want to slowly build my audience on Instagram and start earning some money because the costs of creating this course are significant. What do you think?
