i did physics 1 sophomore year. first semester was a huge struggle and second was a breeze. I got As both semesters and a 4 with no studying outside of class. i am considering taking physics C but i what enough time to do college apps as a senior. I already took calc bc and got a 5 on BC and a 4 on AB. I wna to know if it’s worth it to take. I’ve never taken a real engineering class and I want to see what they’re like and see if it’s something I want to do in college.

I took Calc bc last year as a junior. I got a 4 on the AB section, a 5 in the BC section, and As both semesters. But I also had a tutor iI would meet before tests or for an hour a week. But I don't have a tutor this year. I am thinking about whether I should take Calc 3 this year or not. I studied a lot for calc BC partly because I would procrastinate. I also want enough time to do my college apps. So I was wondering if it is worth it to take Calc 3 and how much harder it is then BC.

i dyed my hair with L’Oréal hi color h3 and h1. I have virgin long thick black hair. I used 4 tubes. the application process for mt hair not including the roots was 30 mins so I only waited 10 mins before putting the dye on my roots. that took like 10 mins and so I only waited like 5-10 mins before rinsing it out. the roots are very light and the rest of my hair almost hasn’t changed at all. idk if I should’ve counted the application time into the processing time but I didn’t want to damage my hair. I used 30 volume developer. how long do I have to wait before using hi color again on the rest of my hair to fix it and how should I avoid this mistake again? also when I redo it should I apply to my roots as well?
