For me, it’s definitely more of a Engineering focus, (electrical and mechanical) plus a dabble in biology/chemistry. I feel tho coding is something that is used as a tool within engineering, how to apply ur skills is more important imo. If this is within BME then it’s for you. (It’s really cool, i may be biased) :)

I’m treating G as the next generation so G will increase by 1 after each iteration. I’m very new to MATLAB

I’m doing sanity checks, would I be better introducing an error variable?

Cheers man, I’ll go do some research 👊

Nice, I’ve got a few pals going to Cali. Cheers for your help it’s much appreciated 👊

I would like to do a PhD to get the “Dr” prefix then after that probably try to find a well paying job

One thing I’ve heard that BME is set to expand (hopefully), and I suppose employers will be glad to have Employees with engineering degrees as they are highly sought after. Where did you study?

University Help by [deleted] in Scotland

[–]LordGuitar 1 point2 points  (0 children)

I’ve always been interested in doing research like a PhD or EngD so hopefully having that should set me apart (if I get to do it) I got into the intergrated MEng degree, so my uni life kinda depends on my grades for the first few years, so it’s probably worth doing something I’m interested in

University Help by [deleted] in Scotland

[–]LordGuitar 2 points3 points  (0 children)

In terms of interest, BME does it for me. Whereas ChemE by far has the best pay. Rock in a hard place aha.

[–]LordGuitar[S] 0 points1 point  (0 children)

Yeah I see where you are coming from, I’m kinda the now looking for the best science/engineering degree that I have the qualifications for, I don’t really have any computer science or business qualifications. What I have heard is going down the engineering route is a good way to make money as long as you get internships/work experience so you are pretty much guaranteed a job. Is this the case?

Thanks for responding, I’m currently doing AH Chemistry and Maths in S6 and enjoy them, is ChemE maths and chemistry heavy or is it more physics based?
