Transferring from a four year school to a community college for second year is mainly done by those who are dissatisfied enough with their current four year school that community college would be preferable to them, and they have a range of other four year schools to apply to as a junior transfer (which would greatly reduce the importance of high school record).
In your case, doing so to apply to one reach school for transfer does not make much sense. However, if your current four year school is unsuitable (e.g. has nothing close to your major, is now unaffordable, etc.), then you may want to do so, but you need to find other four year schools to apply for transfer admission to so that you will have a place to transfer to after exhausting the offerings at community college.
Why did you choose your current four year school, and why is it unsuitable now?
