From the strong verb cheatsheet: given the second, third, and fourth principal parts (i.e. the last three columns on the sheet) of the verbs starting in e, f, and g (i.e. etan up to and including grōwan), be able to produce their infinitive, and also give the verb class and translation.
In addition, be prepared to give just the sense of the words from bēodan to drincan when given the infinitive; you will not be tested on the conjugation or class of these verbs again.
fōr, fōron, faren: faran, class 6 'go'
NB it helps to learn the strong verbs in conjunction with §94 from the textbook or, even better, p. 12 of the f03c slides.
