Affiliate Marketing Secrets

Here’s the situation:
I’m a rising senior, science major in college; I’m trying to decide whether or not to take a physics class this summer to make my first semester next year more manageable and finish premed stuff. However, I also need to finish up classes for my major (neuroscience), which is definitely the #1 priority. The kicker in all this is that I’m not certain about med school yet, so I guess the question is: should I even worry about finishing physics before I graduate?
I hear if you work as a lab tech at a place affiliated with a university, you can take classes fairly cheaply, maybe even one for free, so I was thinking I might do that with physics if I decide on med school. I’m not going to be able to do biochemistry though, before I graduate, so that’s another thing on top of the 2 physics classes that I might need to take later on if I choose med school.
So far I’ve covered
Gen Chem (AP Credit)
Organic Chem 1 (not 2, taking that next year)
Bio 1 (not 2, taking that next year)
Math (stats and calc)
English (Ap credit, etc)
Community Service (I do a bunch at school)
I’m planning on taking 3 science classes both semesters next year which I know is going to be hellish, so taking a 4th class like physics amidst that is not really an option. Hope these are enough details, I don’t want to overload y’all with to much info.
Thanks for your help!

Hello,
I am a 16 year old male looking into starting my own business, preferably clothing ranges. I have already got research done for products i.e. T-shirts and designs and have seen several suitable companies which will print my products, however i am slightly stumped when it comes down to the legal sides of things. I am still in school (Will be leaving in 12 days) and currently studying business and hopefully in college too.
The main question i would like to ask is how old do i have to be to set up a business in the clothing market? How would i set up my bank accounts, as i do not know if i am old enough? I know about book keeping, account keeping etc as i learnt it in my spare time, i just have no idea on some legal requirements.
If anyone can answer them questions and perhaps add more legal requirements if you know of any (Uk citizen) i would appretiate it alot! Thankyou for your time!
