How a lesson works

Read it, spot it, practise it.

Every lesson is one grammar point, in three short steps.

1

Read the rule

The rule in plain words, its structure, and real sentences that use it.

2

Spot the mistake

The mistake learners make most with this rule, crossed out and put right.

3

Practise it

Choose, fill the gap, find the error or rewrite. Each answer is marked at once, with the reason.

The path

Thirty lessons, A1 to C2.

The lessons go in order, from the verb “to be” at A1 to the subjunctive at C2.

  • Every lesson: the rule, its structure, examples and the common mistake.
  • Five kinds of practice: multiple choice, fill the gap, find the error, reorder and rewrite.
  • Here you try one lesson at random. In the app, the path keeps your place.
FAQ

Questions, answered.

Is it free?

Yes. Try a lesson here with no account and no card. The whole path in the WiseLingo app is free while we’re in beta.

Which lesson will I get?

One of the 30 lessons on the path, picked at random, from A1 to C2. Want a different one? Press Try another.

What level is it for?

Every level. The path starts at A1 with the verb “to be” and ends at C2 with the subjunctive. Each lesson shows its level.

Is my score saved?

No — a lesson you try here isn’t saved. In the app, the path remembers what you’ve finished and brings back the rules that slip.

What is Tutor mode?

It’s in the app: any lesson plays as a live class. A tutor explains it out loud, writes the examples on a whiteboard and stops to ask you questions.
