For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
Body regulation on a cold day?
- Vasoconstriction of blood vessels
- no swear
- shiver
- hairs stand on end to trap layer of air
How does vasodilation/constriction work?
- When hot- capillaries dilate so warm blood flows close to skin surface and heat is lost by radiation
- When cold- capillaries constrict so less blood flows close to skin and less heat is lost by radiation
How does sweating work to cool body down?
- sweat (salt and water) is released on to the skin surface
- It evaporates
- heat is lost by convection
How does shivering work?
- Very fast involuntary muscle contractions
- lots of respiration taking place and heat energy is released
How is body hair involved in temperature regulation?
- When cold hair erector muscles contract
- this traps a layer of air next to surface
- air is good insulator
How is blood sugar level controlled by the endocrine system?
- Carbohydrate is digested to glucose
- blood sugar rises above normal
- pancreas secretes insulin hormone (lowers blood sugar)
- Insulin travels in the blood to the liver
- liver turns glucose to glycogen (animal starch)
- blood sugar level returns to normal
- insulin production is 'switched off' (negative feedback)
Blood sugar after fasting or exercise?
- Glucose is burnt up in respiration
- blood sugar falls below normal
- pancreas secretes glucagon hormone
- glucagon travels in the blood to the liver
- liver turns glycogen into glucose
- blood sugar rises back to normal
- glucagon production is 'switched off" (negative feedback)
What is hyper and hypoglycaemia?
hypo- blood sugar low
What are the different treatments?
- Diabetics have to prick their finger and a small machine gives them a digital read out of their blood sugar
- some have to inject insulin
- some have to watch what they eat
Symptoms and risks of diabetes?
- tiredness
- thirst
- frequent urination
- weight loss
- blindness
- limb amputation
- sugar in urine
