Im taking honors math and we have crappy ti-80s the only good calculators (besides my 10 calculators) are the teachers ti-83 NO plus

At my school only a few of the upper level math classes have a class set of Ti-84's and some have a couple Ti-83's.  You are also able to borrow a Ti-83 from our library for the year if you are in AP Statistics.

In my case it was like this:

Grade 10 easy maths (416):
Minimum requirement: scientific calc
What people had: Mostly scientific calcs, but a few had TI-80's, 82's (original model) and 83+'s.
Calculators the class lent: none
Calculators lent at final exam: none

Grade 10 hard maths (426 & 436):
Minimum requirement: TI-82
What people had: Mostly TI-83+'s, a few people had TI-80's and TI-82's as well. Only one redesigned 82 (1996), one 83 and two 83+SE (including mine and a teacher).
Calculators the class lent: 20-25 TI-82's (original design)
Calculators lent at final exam: 20-25 TI-82's (original design)

Grade 11 easy maths (514):
Minimum requirement: TI-80
What people had: Mostly TI-83+'s and 80's, a few people had TI-82's as well (all the original design). I was the lone 83+SE owner.
Calculators the class lent: 20-25 TI-82's (original design)
Calculators lent at final exam: 20-25 TI-82's (PARCUS/3rd redesign from 2001)

Grade 11 hard maths (526 & 536):
Minimum requirement: TI-82
What people had: Mostly TI-83+'s, a few people had TI-80's and TI-82's as well.
Calculators the class lent: 20-25 TI-82's (original design)
Calculators lent at final exam: 20-25 TI-82's (if I remember, they were PARCUS/3rd redesign from 2001)

I believe they got the Parcus 82 models around the end of my final year of hi school. Nobody had TI-84+ nor TI-82 STATS calcs because they did not exist yet. I did not see any other graphing calc model. Teachers had TI-82, 83, 83+ and 83+SE Viewscreen models if I remember.

Btw the only calc models that are sold in Quebec anymore are:

TI-83+
TI-84+
TI-84+SE (rare)
TI-89T
TI-Nspire CX
Casio FX-cg10

Around 2001-03 it was the following:

TI-80
TI-83+
TI-83+SE
TI-86 (until 2002)
TI-89
Casio color screen calc (I believe it was the CFX-9970GC Plus or 9850GC Plus, but it was not the white version)
Another Casio calc that was about $49.99, which I believe was a FX-7400G series calc (until 2002)
HP-39g (when I tried it at Staples it BLOD'd on me) (until 2002)

Afterward they only had 80s, 83+s, 83+SE's and 89's until early 2006 or so, then added Nspires and Casio FX-9750G around Early 2008.

my entire school (±1500) has a TI-84+ instead of me i have a Nspire and a TI-84+ SE

but most people don't need the calc so its pure loss of money.

At our school, we have:
TI-30X II
TI-30XB Multiview (Solar)
TI-83(+)
TI-84+ (SE)
TI-Nspire CX

In brackets are others which are also used.

At my school everyone has to buy a Nspire CX CAS, and before a classic Nspire CAS. About six years ago they had Voyage 200s, but now those are 350 $ (converted to US $).
The school has a Nspire CAS clickpad for every maths/physics teacher and some ancient non-scientific calcs for exams.
But we almost never use calcs in class, and when we use them a scientific calc would normally be enough.

In Quebec I find it ironic that in early hi school we are not allowed to use any calc, in mid/late hi school we can use graphing calcs then suddenly in college we can't anymore again.

Also i never ever saw a Voyage 200 anywhere IRL. Not even a TI-92+ (although I got a 73, 85 and 92 on Ebay). I believe that Consumer's Distributing (anyone remember those stores?) had TI-81's, 82's and 85's when I was kid, along with some Casio calcs. A lot ranged from $69.99 to $129.99 if I remember.

The school has some random scientific calculators, but other than that, we buy them ourselves.

9th grade Algebra 1 and Geometry require any kind of calculator and in Algebra 2 we just need any kind of graphing calculator.
My Algebra 2 class is 70% 84+/84+se, 29% 83+, and 1% nspire cx (me ). I haven't seen anyone in my class with a 89/casio or any other ones.
