WPI yes - you say no constraints but triple check with your folks.
Your three likely are toss ups. You could go 0 for 3 or 3 for 3. But Va Tech most likely, then UMD, then Purdue. All three turn down kids with superior stats to these.
None safe but you have great rigor and maybe that helps.
Michigan is a high reach. You might go TO. While the test is between the 25th/50th percentile, I’d think engineering skews higher.
CMU - highly unlikely.
The last two will be $340-400k - make sure your parents have that.
Have you been to WPI ? Do you love it and the very short terms?
I would add a safety. Meche is about ABET, not rank or name. So pick another sure thing, of which there’s loads.
Good luck.
