Will you be angry if your boyfriend goes on a trip with his classmates and doesn’t take you with him?

If he says that there is no need to introduce you to his classmates, it will appear that he does not respect you very much, which will make you feel sad. But it’s understandable if he finds it inconvenient to take you there, because you are not very familiar with his classmates, and it would be inconvenient for him to be the middleman. I think you need to communicate with him more to see if he is afraid that you will not get along with his friends, or if he feels that your relationship is not yet open to the public. Don't think blindly on your own, and base it on trusting the other party.
