Likely Offers overload, which do I go for?

<p>Sorry for my lengthy post and ????s
I feel I may have applied to so many schools that when the offers start coming, I'd be in confusion deciding which to attend. I did apply to 3 schs in Norway, 1 in Germany, 1 in Holland, 5 in USA (OU,TAMU,TTU,UH,UAF). All in MSc Petroleum Engineering.
I'm a black intl student, did a top 1 in my class (Pet Engr).
I have been admitted by TU Delft (waiting for Faculty Scholarship before June 1), and just yesterday by Texas Tech U (with $1000 Scholarship and eligibility to make InState Tuition Payment). I have till March 31 to decide for TTU.
These are my priority schs in descending order: OU(very sure of TA/RA after 1st semester)/TAMU, TTU, TU Delft, UH, Norway Sch, Germany Sch.</p>

<p>My questions are:
When is the likely period am I supposed to hear from OU(U of OK, Norman with App. deadline April 1) and TAMU(App. deadline's March 31) as I'd like to know their decision before March 31 or Can I write them asking for their decision on my App or Do I ask TTU for extension beyond March 31 if I ve not heard from OU/TAMU (my top choices)?</p>

<p>If I get offers from OU and TAMU without funding in the form of TA/RA, Can you compare their offers to TTU's and TU Delft's (with Scholarship Offer)? Also, do compare based on employability after graduation btw OU, TAMU and TTU.</p>

<p>Any idea about the petroleum engineering graduate program of TTU, OU and TAMU? TAMU is best ranked, followed by OU, then TTU in 9/10th place</p>

<p>The States has always been my number one choice for grad studies but What If TU Delft offers me Faculty Scholarship, Any idea about TUDelft employment potential/history esp. of their petroleum engineering graduates? 2 yrs MSc at TU Delft is looking too much for me compared to USA 16-18months! My family is pretty low on funding.</p>

<p>After Graduation, I'd like to work in the States!</p>

<p>Please your advise and suggestions are highly needed.
Thanks and sorry for ma long post...:unsure:</p>
