I don’t know what I’m doing, how do you guys know math is worth the trouble? How do you cope with failure?

I just failed again for the second time through a master class in numerical partial differential equations (Variation calculus, Finite Element Methods, Stokes, error estimations) and I feel like shit. I always thought numerical mathematics was my speciality but obviously it’s not the case and I feel like doing a master degree was big mistake, despite being halfway through.

I don’t know what I could have done better while preparing for the exam. I’ve done every class excercise mutliple times, I went through the lecture notes multiple times and tried discussing about different solutions the most I can with a friend, who seemed to have done a better job in the exam. Maybe I’m missing something crucial in my exam preparation routine.

So, I’m not sure what the point of this self post is. Maybe you guys have some math studies related stories about that time you hit a wall, or felt like quitting math or maybe I’m missing something crucial in my exam preparation routine?

I checked the rules, and hope I’m not breaking any I misinterpreted

How do you know if you like math enough to major in it?

This questions is kind of absurd. I consider myself a math lover. I really love math more than any subject (except maybe physics). When I work on challenging questions and proofs, I reflect if I am enjoying what I am doing. Then I think about learning other subjects (something like neuroscience) and ask myself if I would rather be doing that. Sometimes I question if I really want to do a math major with this much difficulty and think that neuroscience (btw this is just a random major I thought of) is fine too…but then I am afraid that I will regret not doing the math major.

I apologize if this post is confusing, but in short, how do you know that you are fit to do a math major or that you won’t end up hating it when you are up to your upper level courses?

My first manual: ’02 Saturn SC2

Here it is!

I’m the second owner, only 73k miles on it so far. I gotta say, driving a manual is fun! It’s been just over a week now and I can drive it fairly smooth, much better than the first few days of stalling and tire squealing. Any tips you all have on manual-specific things related to driving and maintenance would be appreciated.

Given the lower miles on this car, I’d like to be proactive with it’s maintenance, I plan on this lasting me a while. What are the best things to do around 75k miles?

Im thinking I should flush the fluids, I know there’s transmission, oil, and coolant, anything else? Also, are changing fluids all as easy as oil? I read coolant requires some tricks to make sure there’s no air bubbles or something, not sure if I can do that on my own.

What about suspension/steering? There’s only 73k mi, but it came from NY and is now in MI so there’s been 16 winters doing damage to the undercarriage with the 17th coming up. I really have no clue where to start for upkeep on all that stuff underneath, used MI cars are usually 150k+ miles deep of rust and neglect, so they end up unfixable beaters and eventually in the scrapyard. I want to avoid that fate with this car as long as possible!

Any comments, tips, tricks, and advice are appreciated!

Showerthoughts: Ford should just lift the Focus and Fiesta ST from the factory, market it as a CUV, and then offer a regular suspension as part of the “performance package”

The Crosstrek had the same interior space as the Impreza pre-Subaru Global Platform with an inch of lift and slightly better angle of attack for the bumper. It’s a miserable vehicle to drive and they’re basically printing money from it. Ford could even include some ineffective AWD on the non-ST models to people who will never go off-roading feel better about inclement weather.
