Welcome to Flexi Tutor Weekly Speller's Flash & Spell. The computer will randomly select a word from memory and flash it on the screen for you to see and remember. Blocks representing the number of letters in the word are displayed. If you can't spell the word correctly, the word will flash for a second time. If you still can't spell the word for the third time, the word remains on the screen for you to copy. Minimum Requirements: CGA, EGA or VGA.
