Sorted by price per hour, cheapest first. Sessions run from 22 to 120 minutes, so the hourly figure is the only like-for-like comparison.

AoPS Online School classes are conducted in a "text-and-image-based" classroom — students read and type in a live chat-style room rather than seeing or hearing a teacher on video — which is a poor fit for younger students, slow typists, or kids who need spoken explanation. AoPS also publishes no maximum class size on its online-school pages.

The advertised $15/class floor is only available on the 12-month commitment (104 classes, billed as a "$1560 coaching fee, billed every 52 weeks"); the 6-month plan raises the same tier to $17/class and adds a "$90 platform fee per billing cycle" that the 12-month plan waives.

The heavily advertised "$17.70/lesson" headline — used in page titles across their whole site — is not a general rate: the pricing page shows it requires the 12-month plan AND states "All prices apply to packages of 2 lessons per week". A 1-month term costs $21.90/lesson, roughly 24% more.

There is no fixed price — their own booking page states "Tutors on Wiingy set their own hourly rates based on experience and subject", so the advertised $19/hr and $15/hr figures are per-tutor floors, and even the free trial is conditional ("most tutors... offer a free trial lesson"), not universal.

Sessions are only "50 to 55 minutes of teaching time", and prepaid packs expire on a fixed clock — the 10-session pack must be used within 3 months and the 50-session pack within 6 months, so unused sessions are forfeited.

The published $50-$55/hour is only an average and is not what you will be quoted: "Pricing varies at each independently owned and operated location" and "Contact your local Sylvan for specific prices" — and their own pages carry three different floors ($49/hour, $50+/session, $50-$55/hour).

The advertised $56 is the bottom of a $56–$99 per-session band, and Learner's own site says rates “vary based on the tutor's experience and level of education, as well as the tutoring package” — so the figure you are quoted may be nearly double. The trial is not free either: it costs $25.

The 4th-grade page is a marketing landing page rather than a purchasable programme: real grade-specific content, but no schedule, no price and no way to enrol — only a lead form. Rates are set by the local franchise, so there is no national figure to compare.

ClassDojo's own site quotes two different prices for the same product — “Starting at $17” on the Dojo Tutor page and “as low as $30 for ongoing sessions” on every subject page — and attaches a duration to neither, while stating classes are “25 or 55 minutes”. The $5 trial is 25 minutes. Until they reconcile that, the real hourly cost cannot be established before you book.

Prices are set by each teacher, not by Outschool, so there is no company rate to compare — listings run $10–$30 per class for anything from 25 minutes to 90. Outschool also adds a marketplace fee revealed only at checkout, behind an account, so the price on a listing is not the price you pay.
