Advise needed - how to get to Grad School without having UG research (Marine Biology)

@STEMFocus Thank you so much for responding and providing those two links. He has targeted Biology labs too, but thanks for the Chemistry suggestion!

@DadTwoGirls Thank you so much for your feedback. We are US, but OOS at UCLA. One reason for graduating early, after he was told so by the Prof., is that this education is expensive and we are worried that after 4 years we are not going to see any return for it. Just closed doors at Grad schools. We don’t live near the coast, so there are no opportunities for him back home to get experience in Marine Biology unfortunately.
