Video star app keeps crashing?

I have an iPhone 5s not updated to newest versions of iOS anyways every time I open the video star app it goes black and crashes after. I do not have my videos backed up anywhere so I can't delete the app or I'll lose my videos on that app. Is there any way to fix this? I've tried to turn it off fully but that didn't even help

Should I drop out of high school and pursue a GED?

Currently I'm a senior in high school who has a GPA of 1.89. The administrators at my school continuously tell me that I'm not going to graduate high school unless I take several night classes everyday until the end of the year.

The education at my school is horrible, down-right dreadful. Everyday I gaze aimlessly at the board learning information that I have learned in the 6th grade. I see other students acting aloof, Snapchatting their friends on their phones while the teacher attempts to teach the class something pointless. This place is definitely not a beneficial place to be at and I know I won't be missing anything substantial if I do drop-out now.

I can't see myself spending another 6 1/2 months at this school doing nothing. Due to my low GPA/ SAT scores, I plan on forgoing the Community College route then transferring out to a 4-year school. However, I do not have an interest in college as well, as I'm pretty sure that it won't help me in any sort of way.

Right now I have a few iPhone/Android apps that are making me over $80k/ year passively. This income has allowed me to become independent from my parents (although I do live with them). I plan on teaching myself HTML and C++ so I can make a website with my friend that will help me generate more money.

Should I drop out? I don't want to go to night school to raise my GPA. What would you do?

Volume not working on my iPhone?

I've tried playing music and my sound just isn't working. Also, no ringtones are working. However, if I wear earbuds, the sound works perfectly. Any ideas?
