Okay, now I see what's behind all the stress. I'm the one who started chiding you for posting so many scheduling & MCAT worry threads as a high schooler. It really works much better if you keep your line of questions to a single thread and stay honest and open.
Overall, it's really not as bad as the stats that school posted. (The stats were interesting. Do post where you found those.) Yes, many more students enter college calling themselves premed than actually complete the path. Perhaps the main reason for that is that they think it sounds cool, but don't have any idea that success requires more than just a declaration. Desire, ability, determination, and WORK are a much larger part of the formula.
That does not mean that you have to machete your entire path now, as a high schooler. However, taking the time to understand the steps now, instead of 3 years down the road, will be helpful to you.
Really, you do need to stop stressing. Focus on getting into college and having a successful senior year. Read threads. You'll learn a lot just by doing that. Don't be stressing about ochem now. It's not that bad if you're interested in the subject and study effectively. If you do well in bio & chem before that, you'll probably do just fine. Having straight A's in college will NOT make or break your application.
Some questions for you - What major interests YOU most right now? You mentioned psych in another thread. That's a fine major. You can do that and get your prereqs in. No need to major in bio, chem, or biochem. Take classes that interest you. That's important to your life in college and beyond. What is your high school record like - what types of courses have you taken & what how has your overall performance been? Are you an only or eldest child? An only son? Why are your parents pressuring you? Have they been like this all your life, or just over med school? People can give you much more appropriate replies when they understand the background.
You do not want to be stuck in medicine, or any other profession, just because your parents expect it of you. You'd be miserable and your parents really wouldn't be any happier. They have to find their own happiness. They can't live their dreams through you. Making it to MD is something you have to want for yourself. You have plenty of time to test the waters between now and when you would apply. College is supposed to expose you to new experiences and ideas. You'll have the opportunity to think and rethink about suitable life paths. Your parents will become less influential.
Hopefully people on here can help destress you. You seem to have already internalized too much pressure.
