The stem would be \"heb\", and that is the form you need: ==ik heb==, jij hebt, wij hebben. In your email, \"ik wil graag een afspraak maken\" is correct because \"wil\" is the verb that goes with \"ik\". \"Maken\" is a second verb and stays in the infinitive.\n\nThe exam checks grammar on a writing task like this.
