There are a number of things to consider when choosing between the two degrees. Below, are details about each major, their differences and reasons to choose one or the other.
Details about a mechanical engineering degree
Below are some details about a degree in mechanical engineering.
According to Payscale, the average pay of a mechanical engineer is $80,251. This is higher than the average pay of most degrees including most engineering degrees including civil engineering. However, it is lower than the average reported pay for computer engineering ($87,000), electrical engineering ($92,000), and computer science($85,000).
The predicted growth rate for mechanical engineering jobs is 4%, in total, over the next decade and the number of mechanical engineering jobs is said to be 320,000 (source). This, by itself, would give the mechanical engineering major moderately good job prospects.
However, mechanical engineering can also qualify you for jobs in related fields including industrial engineering which has a 10% predicted growth rate. This means that mechanical engineering can have good job prospects, provided that you choose to take classes relevant to areas that are growing and which already have a large number of jobs, at least above 300,000.
Jobs you can qualify for with a bachelor’s degree in mechanical engineering can include:
- Mechanical engineer
- Manufacturing engineer
- Design engineer
- Project engineer
- Aerospace engineer
Mechanical engineering is a difficult major. It will include a lot of math classes, a lot of physics classes and the mechanical engineering classes, themselves, can be difficult which also include a lot of physics and mathematics. Overall, you can expect mechanical engineering to be a lot more math heavy than biology.
Below are some classes you can expect to take in mechanical engineering:
- Differential equations
- Fluid dynamics
Things to consider
Mechanical engineering is a major that will involve a lot of study time. If you are choosing the major purely for the job opportunities, there are better alternatives that do not require as much study time such as computer science.
However, mechanical engineering can be a pathway into very interesting careers that are very satisfying. Before choosing mechanical engineering as a major, it would help a lot to research the different jobs you could get and to see if they are things that you would truly enjoy doing.
Details about a biology degree
Below are some of the key details about a degree in biology.
According to Payscale, the average pay for a person with a degree in biology is $71,112. This is better than the average across all majors. However, something to consider, is that the average will be being increased considerably by people with master’s degrees and PhDs in biology.
Biology can be a somewhat general degree that is not specialized towards specific job roles. As a result, it is often necessary to combine biology with a more applied minor or to get an advanced degree after graduating, in order to make the major more employable.
In a ZipRecruiter survey, it was found that 35% of biology graduates regret choosing the major due to difficulty finding a job without an advanced degree.
With that being said, the major can be a gateway towards jobs in a number of different fields, but it will often require some extra studying to become employable in those fields.
According to Payscale, people with a degree in biology often get jobs as:
- Lab assistant
- Physician assistant
- Biomedical engineer
- Physical therapist
- High school teacher
Note that many of these jobs will require at least a master’s degree.
Something to be aware of is that many of the jobs that require advanced degrees do have strong predicted job growth (source). This is encouraging if you are set on getting an advanced degree in biology. However, something to be aware of is that if you change your mind halfway through, it could be difficult to find a job with just a bachelor’s degree in biology.
Biology is a difficult major. The biology classes themselves can be difficult and the major will usually require math, statistics, physics, and chemistry classes. Overall, you should expect to have to put a lot of time into the major.
Classes you can expect to take in a biology major can include:
- Introduction to physics
- Introduction to biology
- Molecular biology
You can look here to see an example degree sequence.
Things to consider
Alternative majors can allow you to enter medical school but also have good job opportunities. In fact, because it can be difficult to get a high GPA in biology, alternative majors can actually be better for medical school because having a high GPA can help a lot.
To get the more desirable jobs, in biology, it is often necessary to get a PhD. If you do choose the major, it would help a lot to consider combining it with a more employable minor in order to improve your job prospects after graduation.
When deciding on whether or not you should major in biology, it would help to consider whether or not you are set on going to graduate school as well and the types of jobs you want. If you are set on going to graduate school and you want a job that will require a master’s or PhD then a biology major would become more worthwhile.
Reasons to choose a mechanical engineering major
The key advantage that a mechanical engineering degree has over a biology degree is that it is a very employable degree by itself. This is because the degree directly applicable to a number of high-paying jobs at the bachelor’s degree level. Whereas, a biology degree needs to be combined with something more applied in order to make it as employable as a mechanical engineering degree.
Also, mechanical engineering jobs tend to be very satisfying jobs that are also very interesting and important to society.
However, a mechanical engineering degree will require a lot of study time. There are some alternative degrees that can also give good job prospects that do not require as much study time such as computer science. If you are not sure that you would actually find the material in a mechanical engineering degree interesting, it might be the case that an alternative would suit you better.
Reasons to choose biology
While it can be difficult to find jobs with just a bachelor’s degree in biology, there are still some reasons why you might want to get a biology degree.
The first reason is if you want to get a job that requires a master’s or doctoral degree in biology. If you do, then a bachelor’s degree in biology would be more worthwhile.
Also, if you have a very strong interest in the subject, it would also make it more worthwhile for you to major in biology. However, it would also help to minor in something that is employable at the bachelor’s degree level.
