8,275 Pointsso you have a user table, words table with two fields english & russian, quiz table which holds info about user quizzes, and finally a user_quiz or something that links quiz table to words table so that you know which words were in which quiz.
This way user can have multiple quizzes open and when you assign a new quiz, just make sure that you don't give user same word....
Actually one bad thing about this design is the words table.. you shouldn't have two fields or design it like that unless you are 100% sure you won't extend this to another language say French etc.. because if you do that, then there are better ways of doing that such as:
words id, language, word, parent_id
parent_id is the id in words table for a word in Russian.. so if you had <Welcome> in Russia, if its id = 1, when you translate <Welcome> to English, you would give it 1 as parent_id so that it is easier for you to reference.. this way you can extend your quiz to other languages..

8,275 PointsI have no idea what your project is about even after reading your post.. but clearly you are right creating 1000s tables for each user is a bad idea...
what does this mean:
"my target is to create quiz for memorizing english words?"
what are the requirements or how does this work..

then next time he is trying to pass the same quiz or test whatever. My target here is to know if the user is already know current words, if he knows so i wont give him points for that.
sorry for my english , I'm not a native speaker
