Hi all my thoughts, and others :)
Almost 5 monthes has gone since my previous message. I've tried many things. But unsuccesfull. Approximately one month ago I've faced with my lack on English again. And seriously indeed.
Once was professional conversation with native speakers. And even in writing skills I feel unsure. Oral communication I didn't try even.
On what I'm endeavouring now:
english-test.net
Alice in wonderland.
Database Systems - The Complete Book (Molina, Ulman).
