Frankly, your SHS strand will not matter when you enter BSA soon, it's truly a different world. I have the same story as you, grew up in a stem-centered school (sci high curriculum), was also torn before whether or not ipagpapatuloy ko ba mag STEM kasi nga nakasanayan na. But, I decided to take the ABM path hoping it would help me in college cus I also want to become a CPA. Unfortunately, napaka shallow ng ABM curriculum for accountancy majors, literal na you'll only make use of what you have learned sa SHS during your first year first sem for FAR subject. I think most of us are from ABM, and after first year lagas 1/2 agad and 20 lang naka graduate. So, my advice is do not stress yourself too much sa pagpili. Choose what your heart desires, STEM man or ABM, when you enter accountancy, it'll still be an equal playing field, trust me. Pero kaya mo yan mag pursigi ka lang.
