<p>I think I can answer most of your questions.</p>
<p>No, you don’t need a diploma, as long as you were being home schooled legally in whatever state you live in, then you’re fine for 99% of schools. (There are some schools that require an accredited diploma, but it’s not HPYS; it’s mostly schools that deal with the bottom quartile of students.)</p>
<p>Also, you have a ‘transcript’-- the record of classes you took while home schooled and your grades in those classes. This, of course, counts for jack, (no college is going to admit you on the basis of your stellar ‘home school’ GPA); but, you don’t need to injure yourself in trying to replicate the transcript of a traditional student.</p>
<p>Colleges – especially selective one – will asses you academically based on your test scores. So, take it seriously and take a lot of tests. The SAT and the ACT is enough testing to get you into most schools, (though not a lot of the crazy selective schools CC tends to be obsessive about-- you need to be a stand-out for that); however, if you’d like to demonstrate your academic fitness to a college, then take a few SAT subject tests.</p>
<p>But, to answer your question simply: Yes, you can ‘get away’ with just taking more tests, but if I were you, I wouldn’t go for a GED unless you absolutely need one to get into a particular school.</p>
<p>Also, just a personal anecdote:</p>
<p>When I went to my local community college to register for classes, I had the lady handling my admissions leaf through a packet of my work, some test scores, recommendations and a listing of all my courses and say – as if I was hiding something from her – “Where is your transcript?” I explained to her that the state doesn’t keep a transcript for me – as I’m homeschooled – and that the packet she was holding was my transcript.</p>
<p>To cut the story short: I ended up sitting for a placement test that day, got a very good score and found the faculty way more accommodating after that. So, OP, I can see how you’d get freaked out about your transcript but, seriously, don’t sweat it. Take a bunch of tests, get an idea for where your scores fall and apply to some schools. Happy college hunting. </p>
