How do you know if your English is actually improving?

Most people just guess. They watch Netflix without subtitles and think “I get more now.” Or they feel a bit more confident speaking. But feelings can be wrong - and without proof, motivation fades fast.

That is why Naitly tracks your CEFR level and shows your growth step by step. You can see what changed since you started and what is still weak. When progress becomes visible, you know the work is paying off.

How do you check your own progress now? Do you use any online tests, ask teachers, or just trust how it feels? Have you found a way that really works to measure improvement and keep yourself motivated?
