My mom grounded me for something that's not my fault. Is this fair?

I'm a freshman in high school and I'm in AP Human Geography. I had a 90 first term and now I have a 60 for 2 reasons.

First I turned in one of my minor homework assignments but my teacher lost it and gave me a 0 to cover the grade. Now when I ask her about it she said that I have to redo it for a 70, not even full credit, AND SHE LOST IT. So I redo it for a 70 and now my mom blames me for it somehow…

Second I got a 0 on another minor homework assignments just because I forgot to put my name on it and now I went and put my name on it for the 100 points but my mom thinks I don't do my work now that this happened and I told her I forgot to put my name.

I know that me being a freshman is scary for her because it's the first year things start to count for my future and she just wants the best for me, but this time I think she went WAY, WAY overboard. She took my earbuds, iPhone 5, uninstalled my favorite thing ever, my video game, and she left me my computer for only homework purposes. I also have a 100 major grade being put into the grade book, but my teacher takes forever or something because I redid the thing she lost last week and she still hasn't updated the 0 grade and I did the major grade for a guaranteed 100 like 2 weeks ago.

Please tell me what you think and what I should do.

I think you should be grateful that your mother cares and just chill. You will survive for a week or two without your earbuds, apps, social media, and phone. During that time do your best to get ahead on your reading or other homework.

At some point, you can invite your mother to meet with you and your AP teacher to review where you are in the class. When things have cooled down, you and your mom can talk about how you are doing your best and have learned from your one mistake. You can also explain that during high school you need to learn to take more and more responsibility for your choices and your actions and you plan to do so responsibly.

Moms (and Dads) freak out because they know that a teenager simply doesn't fully appreciate the potential consequences of their actions. It is hard for parents to let go. You may see your punishment as unfair, but it really isn't the end of the world. The keep is not to create drama and to calmly ask what you need to do to reestablish trust and earn your way out of being grounded. Then do those things.

Although the teacher is busy, she will understand your reason for being anxious about getting the grade updated. Talk to her and tell her that the length of your punishment is being affected by the grades not getting posted. She doesn't want to be responsible for your suffering, and is likely to handle it as quickly as possible. On another matter, your irritation with your mom's reaction is understandable. It isn't your fault that the teacher lost the assignment which you turned in, and the "forgot to put my name" bit happens to a lot of people. None of what you describe is dishonest or criminally careless. But your mom is the way she is, and she is going to be extremely concerned about your performance for the foreseeable future. Show her that you are a very responsible individual. Earn top grades this year and next. At the end of your sophomore year, when you can show her two years' worth of superb performance, have a conversation with her and ask her to be more flexible with you. She'll be more open to the idea if it is supported by proof of your dedication.
