Necessity statements

[beltspinner.livejournal.com]

My teacher did not explain this at all, and before I go into her office to try to get extra help, I thought maybe you guys could help with this list of synonyms of надо/нужно and должен

I don't understand the underlying meaning of the different versions.
вынужден
пришлось
придется
должен быть
наверное
наверняка видимо
по всей видимости
необходимо
следует
стоит
требуется
испытувает потребность
нуждается

I know it is a lot, and I appreciate your help.

Russian typing tutor...

[sbgskl.livejournal.com]

For those of you just starting with the Russian Standard Layout... I found a nifty Russian typing tutor site. It works in any browser with flash. Pretty convenient if you float around various computers (school, work...) throughout the day and want to get some practice in.

It's set to english by default, to change it to russian click the small "Language/Layout" label near the top (to the right of the keybr.com logo).
