Would I advise yourself getting a placement? DEFINITELY YES.
Is it necessary? No but it will make your life A LOT easier once you graduate as I got turned down A LOT for "not having work experience", even for the Band 2 jobs (you can't get lower on the pay scale). I would almost certainly recommend getting a placement in an IBMS course and lab as there is a chance that once you leave placement, if they like you enough, you can go back and start/finish the portfolio (I have heard some people got super lucky and completed their portfolios in their placement meaning as soon as they graduate, they can become BMS.

Is there a lot of chemistry? It depends on your subject specialism. I personally went down the Clinical Biochemistry route and it is NOTHING like A Level Chemistry which I absolutely HATED as in you don't have to worry about complicated chemical equations, just what is in the blood, diagnose where it has likely come from and eliminate the causes of said condition as well as other conditions. I have attached an example of a question (it is Masters Level so don't worry about it too much) but this is just to give you context of what Clinical Biochemistry is like, I have also included the first page of my answers (1,500 word essay), with my lecturer's name(s) removed for the sake of privacy.

Schedule varies from uni to uni, so I wouldn't worry about that. My lectures are all 3 hours long and I would typically have one, SOMETIMES two per day with an hour in the middle. Every hour of lecturing would typically give us a 15 minute break.
The generic consensus for marks is for every credit you want to achieve, you must do 10 hours of material (self taught and lecture). So if you had a 30 credit module, you would be expected to do 300 hours of revision for said module.
Example of the chemistry you'd be expected to do at MSc level (it is not too indifferent to BSc, just more in depth and they go harder at MSc vs BSc i.e. What would be deemed a distinction at BSc would be the bare minimum pass at MSc. What I have included achieved a (bare minimum) distinction at MSc level.
