Exactly. Miss Lien is correct. In almost all cases zullen = shall. It´s main uses are proposals and promises
Ik zal mijn huiswerk maken ( I shall make my homework)
zullen we dansen ( proposals).
Note that ´zullen´ as wel as the other modal verbs (willen, kunnen, moeten, mogen) has a irregular conjugation in the present.
Ik zal
jij zal/zult
Hij zal
wij zullen
jullie zullen
zij zullen.
´Zult´is more old fashioned than ´zal´, but it is still used a lot in Belgian spoken language.
Succes met je studie !
