Is there a difference between a Regents Diploma and an Advance Regents Diploma?

My brother failed Geometry 2 with a 61 (on both his regents and class) and he's a junior in high school. Because of this, he will have to go to Summer School and retake the regents in August. However my brother does not wanna go to summer school and rather just repeat Geometry in his senior year. But he is supposed to be taking Algebra II/Trig. next year and if he doesnt take the Trig regents, he will only recieve a Regents Diploma instead of an advanced one. My question is does it look bad in applying for college that you repeat a course you have no future in whatsoever (he actually wants to study Geography and History in college)?? and is there a negative in recieving a Regents Diploma compared to an Advanced one??
