I can’t speak to their other courses but we have been taking French courses through Sterling Academy online for the past 5 years. They are accredited and pricey but we like their teachers and staff. Occasionally their software has glitches but they seem to resolve them quickly. I just signed up my younger 2 for Sterling’s middle school French classes.
Also, my high schooler took physics last year from Nebraska University online High School. They were highly recommended by friends who are teachers. It’s worth looking into whether NU offers elementary courses. Ds said their physics course was rigorous.
