No, that would be arctic engineering.

RPN for the win.
I always had a RP calculator as an undergrad. It kept people from asking to borrow it. Started out with an 11C and finished up with a 42S.

Still use my HP48.....it is getting kind of glitchy though, so I think it's days are numbered.

Classic TI89 is what I used.

The TI-89 Titanium is an impressive calculator, but see if you can play with one first before dropping $125 on it. It's way different from the RPN machines. The built-in engineering programs with all kinds of calculations out of the box are nice to have if you're in the field and need a down and dirty calculation.

This is what my wife uses, she's a senior at Ga Tech, Civil Engineering. Whatever that means, I'm a liberal arts grad, so I don't do anything but basic math.

This was my first calculator, 1975. Expensive as hell for the time.
For the last 25+ years it's been the 32S. Discontinued in 1991 but I bought a backup and the original still works fine. No need for anything fancier for the work I do.

The ability to invert matrices with imaginary numbers comes with the 89 Titanium and better models so save some money and just get that one out the gate

Get a TI 89 and learn how to use it. They are powerful tools.
This.
Derivatives, power series, matrices, differential equations, integrals...
It's very good.

Try a Casio FX 115 for systems of equations.
When I was at Tech, they forbid students from using graphing calculators for exams (at least at the sophomore level for certain classes).
Now if we're talking on the job, TI 89 dominates in my opinion.

This is all you need

TI 89 is great, but.....
A couple people said it already...
Get the TI 36x pro.
That is the highest level allowed to use on the FE exam down the road. May as well learn it well ahead of time. And it's actually a really good calculator.

I have a perfectly functioning HP 48G and a TI-89 Titanium. The TI-89 is a powerful little machine though if I was going to drop the coin again today I'd be looking at the SwissMicros DM42. It's RPN and based on the HP 42S but uses open-source programming.

My hp 32s bit the dust years ago and never found a replacement that I liked. Was able to download a hp 32s app and am now back in business!
