Good luck! And remember that you can always switch majors in college. Almost all of my friends made radical changes, such as engineering to nursing. I had a bit of an advantage since my dad was an engineering professor and I knew what I was getting into. 
Not only can you switch majors, but you also don’t have to apply to the same major at every place you apply. Choose programs you like and keep several options open.
During Fr/So year in engineering (DD is Civil and Architectural Eng double major and graduated May 2018) one takes Physics I and Physics II (both with calculus) - so during PH I the calc 2 material was used – so DD was encouraged to take both of these courses in the same semester - which she did, her spring term as a freshman. She ended up taking Honors Calc I her first semester in college to solidify calc knowledge base – her high school didn’t have Calc C/D so she took Senior year Statistics and then refreshed in her first term of college with calc. Her college has a very big football program (in the SEC) and she was in the band all four years - and the two physics classes did not come easy to her so she took them both on spring term. During her junior and senior years, she just had to suck up taking what she needed during each school term to finish on time.
With any of the engineering degrees, you pretty much have to complete almost a math minor in college.
I suspect math doesn’t come easy to you, or you need excellent instruction to ‘get it’.
So you may want to go for plan A but keep a plan B and C in mind.
DD needed to keep her GPA up for her 4 year scholarships (full tuition, and also engineering scholarships) which she did - I encouraged her to have as high a GPA as she could early on, to soften a passing but lower grade in some of the harder classes - which she was able to do.
One has to start off college with a good strategy to keep the scholarships. One doesn’t want to waste time and money floundering around to various majors - and many schools will have a lay out of degree plans to ‘finish in four’ so you can see how classes towards one major can be applied to another if you make a switch.
