If your dragon is under 4 months old , I'd be ensuring at least a morning feed and an afternoon feed.
Invest in a smooth surfaced porcelain feeding dish like this

, you can leave a few dozen large BSLF or some small ( about 1" long ) silkworms on some mulberry leaf or chow in the little dragon's tank first thing before heading off to lectures , the dragon will soon discover these and pick at them during the day.
Tip - make sure the bowl has a small overhang on inside rim and make sure the BSFL go into dry (if they are the least bit wet, they will escape the bowl, simply, make sure the bowl is clean and dry before they go into it.
Set the lights to come on about 6am or 7am, the dragon will be awake and warmed up and ready to eat by the time you either place the feeders in the tank in a dish or when you get up to drop insects like crickets or roaches in a few at a time ( I've never had a feeding session last more than 15 minutes ).
