Helped me get through school. All the cool engineers had one. Really the only reason i got it was for solving integrals during electrical engineering exams because by that point in school professors aren't trying to figure out if you can solve an integral. They care more about whether you can set it up properly abd give a correct answer. Gonna be honest, though, during my job if i had to solve an integral I'd just use wolfram alpha instead. I'd use my lightweight ti-36x pro on a normal basis. Works great, lightweight, and what I'm most familiar with because it's the best calculator you can use that's still usable on the national exams. Great for on the job calculations.

I had one for nearly 7 years before it broke, and had no problems during that time. This one is a replacement for it and I love it just as much. I am an engineering student in college and I would not have been able to get through the coursework without this calculator. It is intuitive to use, and very powerful with excellent battery life. This might be a little too much if you are just doing basic math classes so you would probably be better off saving your money, but if you are going into something math and science heavy, this calculator is worth every penny
