What does “free” mean for each offer?
Teachero advertises its preparation as fully free, with no paid version or expiring trial. That is an advantage for applicants with no budget for prep. We are reporting the provider’s description; we have not explored a full account to verify access to every feature.
Upsilar Free covers one test, with gradual access and quotas. Some access rights renew monthly; others are available only at the start. The plans page explains this distinction. It would therefore be inaccurate to present the two free offers as full catalogs with identical access.
As of October 15, 2026, Upsilar’s paid plans are listed in the catalog, but purchases are not open. Their availability and terms should be confirmed when you make your choice.
What should you compare beyond the price?
Public descriptions can help identify use cases. They do not show that one explanation will be clearer to you or that one prep option leads to a higher score.
| Criterion | Upsilar Free | Teachero |
|---|---|---|
| Advertised model | Free, gradual access, with quotas | Fully free, according to the provider |
| Organization | Topic-based path | Study plan advertised |
| Explanations | Lessons and method examples | Lessons and written or video worked solutions advertised |
| What to check | Access included in Free | Access that meets your needs |
| Evidence of outcomes | No comparative gains established here | No comparative gains established here |
How can you compare two free resources without spending days on it?
Choose one specific difficulty instead of browsing every section. For example, you may confuse two successive increases with adding their rates. Find an explanation, try an exercise, then restate the rule without the resource. The next day, try a different problem of the same type.
Write down what helped: a calculation step, a diagram, a counterexample, or a correction to a mistaken assumption. Also note what stopped you: vocabulary, navigation, a missing explanation, or lack of time. This gives you a personal comparison for a concrete use case without assigning an overall score to a platform you barely know.
Repeat the process with a different topic. A resource may work well for calculation but less well for reading comprehension. You do not need to choose a single resource for every purpose, but keep your priorities in one place so you do not lose focus.
The pitfall
Treating a platform estimate as an official result
Teachero presents score estimates and projections; we do not use them to compare prep effectiveness. We also do not repeat its question counts, which vary across sections of the page we reviewed. These figures are not needed to determine whether a worked solution helps you.
A practice result depends in part on the questions encountered and your testing conditions. Instead, look at the mistakes you can explain and the time you used. The TAGE MAGE score is the one issued after the official test, not a promise calculated from a few exercises.
Do you have to pay to prepare seriously?
Not necessarily. If a free option helps you understand, practice relevant topics, and stick to your study sessions, you do not need to spend money to prove your commitment. Paying should address a specific gap, such as instructor support or content you cannot otherwise access.
On the other hand, keep in mind the limits of independent study. If you still do not understand your mistakes after reviewing several worked solutions, look for an appropriate discussion. This might mean a teacher, study group, or someone who can check your reasoning; this need is not limited to choosing between these two platforms.
We recommend starting with the resource that seems most accessible and observing how you actually work with it. Keep it if it suits you. Switch tools when an identified difficulty warrants it, without confusing a new dashboard with progress in your method.
Key takeaways
- Teachero advertises fully free prep; Upsilar Free offers gradual access with quotas.
- Compare worked solutions using your specific challenges.
- Paying is useful only if the service addresses a need that is not yet met.
