Are you ready for PHSI191 physics at HSFY Otago?

Nov 8
The PHSI191 paper is the physics paper you must take as part of Health Sciences First Year (HSFY) at Otago University. This paper is challenging for many students, and can prevent these students from getting into medicine or dentistry. Find out how ready you are for PHSI191 by reading this article and using my decision tree.

How much physics do I need to know?

HSFY is notorious for being content-heavy. There is a lot of content that is covered in PHSI191, and a lot of it will be new for high school leavers. 6 modules with the following topics are taught in PHSI191:
1. Mechanics
- Vector addition
- Kinematics
- Dynamics
- Mechanical energy
- Centripetal force
- Momentum
- Torque
- Simple harmonic motion
- Waves

2. Solids and fluids
- Young's modulus, shear modulus and bulk modulus
- Pressure
- Buoyancy
- Non-viscous fluids
- Viscous fluids
- Diffusion

3. Thermodynamics

- Thermal expansion
- Ideal gases
- Thermal equilibrium
- Heat transfer
- Phase changes
- Efficiency
- Psychrometric chart
    4. Electricity
    - Electrical fields
    - Electrical circuits with resistors
    - Capacitors

    5. Optics
    - Refraction
    - Lenses
    - Diffraction
    - Circular apertures

    6. Radiation

    - Photons
    - Ionising radiation
    - Orbitals
    - Mass defect
    - Decay
    - Biological radiation dose
As you can see, mechanics is the heaviest module and this is likely because they assume you would have covered all of this already. You can access the Mechanics module on my A+ PHSI191 online course for free by clicking here - [Free] A+ PHSI191 Online Course Mechanics Module.

For those that have done NCEA Level 3 Physics, I would estimate that roughly half of the content would be new. The level of difficulty of the physics taught is largely similar to NCEA Level 3 Physics, however the breadth of topics covered in such a short time is what makes it far more challenging than high school physics.

If you have only done NCEA Level 2 Physics, then you will encounter much more new information. Those that have studied physics prior to starting HSFY will be at a significant advantage relative to those who haven't. The better you are at physics before starting HSFY, the easier it will be for you to get a good grade.

How do I know how ready I am?

I have developed an algorithm tree above which you can use to determine your readiness for PHSI191.

If you have not studied physics at all before then I would say your readiness level is LOW. It will be very difficult to get a decent grade, even with a lot more time and effort on physics than others. Not only this, but you will have to spend so much time on physics during Semester 1 that your other papers will likely suffer. I would highly suggest studying physics prior to starting HSFY. There are multiple options available for you to do this, including my A+ PHSI191 Online Course. You can check out my other blog post here - How can I prepare for PHSI191 Physics?

If you have done NCEA Level 2 Physics but you didn't do very well in it, then I think you will have a LOW-MEDIUM readiness level. This means that you will have to put in a lot more time and effort during the semester to get a decent grade.

If you have done NCEA Level 2 and gotten Excellences in it, or you've done NCEA Level 3 but haven't done very well in it, then you probably have MEDIUM readiness. Although you will probably do ok at physics with a reasonable amount of effort, you will be at a disadvantage relative to those with high readiness.

If you've done NCEA Level 3 Physics and managed to get Excellences, then you will have HIGH readiness, giving you an advantage relative to others. However, you still need to learn a lot of new content so you should not slack off on physics. I recommend aiming for 100% on this paper as this is definitely achievable for you. This will boost your HSFY average and give you a much better chance of getting into medicine or dentistry.

Don't despair

Even if you've never studied physics before, you can achieve an A+ in physics. I guarantee it. Literally. 

If you take my A+ PHSI191 Online Course and you don't achieve an A+ in PHSI191, I will give you a complete refund of everything you paid me. You can achieve a lot in a short amount of time if you knuckle down and put in the hard yards. But not only must you work hard, you must work smart. I believe that the best way for you to work smart and improve your physics grade in the shortest amount of time is my A+ PHSI191 Online Course. Learn more about it here.
