How Blindspot finds your blind spots
Your text
Yesterday I didn't saw my friend at the university. I was waiting for him near the library but he came only in the evening. He said he was busy because he готовился for the exam all day.

You can't fix mistakes you don't notice
- You google a rule, fix one sentence, then make the same mistake next week
- You "know" articles and prepositions — but still get them wrong every time
- Generic exercises drill grammar you already use correctly
- No one tells you which mistakes you actually keep repeating
Blind spots become lessons
- 1Write anything — your blind spots get caught automatically
- 2Rules and vocabulary come from your real mistakes, not a textbook
- 3Practice targets the patterns you keep repeating
- 4Everything in one place — your blind spots, your progress, your dictionary
Your blind spots show up everywhere
