Affiliate Marketing Secrets

I’m starting a YouTube channel soon where I plan to do makeup tutorials, beauty product reviews, updates on the latest /best priced items, etc & I wanted to do a “giveaway” (give away FREE nyx makeup) on instagram hoping to get more followers on instagram & promote my youtube page. One of the rules to enter would be to subscribe to me on YouTube & they must be following me on instagram. Then I would choose an end date for the giveaway & randomly choose a winner ! I would pay for the shipping also (giveaway would only be for u.s citizens only, not international)
My question is: is there any laws or regulations about me doing a online giveaway (100% free) using products that aren’t made by me ??? But I did buy them. Would I have to state that the items were purchased in store by me & not supplied by the company ? & that i am not affiliated with them in any way ??? I’m asking just to be on the safe side. I see it done allllllllll the time on instagram but before I do it, I just want to be sure that its legal
Pleaseeeee help !!! 🙁

I am getting regular emails to buy and join. I am still with more doubts and dont want to loose my money. Pl give full idea to say Yes or No.

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!

I wanted to ask that a private university would give the same degree as the state university or it would provide a different degree as from the state. A private college affiliated to state university gives the degree of the state university but what is the condition for private university in the same state. Will it give the degree same as state or a bit different
