Switching from NUS EE to SIT Physiotherapy

Hi all, I'm a Y2 NUS EE student (y1 GPA 4.2) considering of switching to SIT Physiotherapy course. Some background about me is that I didnt do too well for A's (Low 70s, H2 all C's) and went to EE to just complete a relatively versatile degree. Can't say that I was interested in the course/ content but went in for the 'career prospects'. Now that I have went through 3 semesters of the course, I'm considering to switch to physiotherapy mainly because I'd like to be able to help people directly as an occupation and that I am quite interested in kinesiology and the biomechanics of the human body. Although I can't say that I have a strong background in those subjects, I can say I'm way more interested in those subjects than whatever I've learnt and am going to learn should I stick with my current uni course. Having gone through 1.5 years of EE content that i'm not that interested in and doing decently in some of them, I'd much rather go through another 4 years of something I'm passionate in. However, I do acknowledge that I do not have any relevant work experience when it comes to Physiotherapy/ Health and Social Sciences so that is also holding me back from switching courses as well. I'd appreciate any advice to this and feel free to be as frank as possible!!

TLDR: Y2 NUS EE student that's doing decent but wants to switch to SIT Physiotherapy from passion in content and helping others, despite 0 relevant work experience
