Swansea pathway to medicine

Is anyone on Swansea's pathway to medicine course where you do an undergrad for 3 years and then you get a guaranteed med offer? I've been put on populations health and medical science through clearing so I can do this but I genuinely don't know if it will be worth it considering others doing undergrad medicine will be graduating after 5 years whilst it will take me 7 !! I achieved CDD and my chem grade was one mark of an E - so essentially an E... I am thinking of resitting but I am worried I won't be able to get A/B during resits since I revised really really hard for these exams and only came out with Ds and Es for the sciences. I was put on private courses and had private tutoring so I am very concerned as to whether I can even achieve a B through resits. I also wouldn't know what to apply for since medicine and dentistry would be out of the picture. Possibly pharmacy? MY school is no help
