- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
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.
Explain veridicality in light of ecological validity of NP assessment
How is the worksetting of a pt. related to his strengths and deficits
Why is it important for a NP to obtain information about demand characteristics of pt environment
What is a major problem in ecological validity with environment of testing?
What is ment by conditionality in the paper by Sbordone (2008)?
What causes a problem with ecological validity of pt. completing a questionnaire about complaints? How can this be solved?
What assumptions are held by some NP which cause difficulty in translating data to real-world settings?
How is, according to Sbordone (2008) NP testing currently used?
2. Determining whether brain damage is sustained
Name 2 limitations of NP testing suggested by Sbordone (2008)
2. Many cognitive deficits go undetected because NP rely on standardized neuropsychological tests
Is the use of IQ tests promoted by Sbordone (2008)? Explain.
Name confounding factors for poor performance on testing
neurological conditions
seizures
acute pain
symptoms secondary to injuries
illness
sleep
fatigue
alcohol drug abuse
medications
psychiatric illness
stressors
motivation or malingering
negative interactions examiner
cultural
tests
practice effects
Why are neuropsychological tests poor in assessing functioning of the frontal lobes of brain
Patients with damage to medial orbital frontal lobes often exhibit loss of motivation, energy, and drive, pleasure, depression, psychomotor retardation, change eating habits, loss sex drive, curiosity and obsessive compulsive behavior. Patients above will deny symptoms and test within normal ranges but exhibit dramatic change in personality. Not observed by NP because spending little time with patient
Name personality changes often associated with frontal lobe damage.
2. Egocentricity
Poor frustration tolerance
Mood swings
Explain why NP tests are poor in assessing executive functions of the brain?
Includes awareness that problem exists, evaluation of problem, analysis of conditions of problem, formulation of goals to solve problem, evaluation effectiveness of plans, selection and initiation of plan, evaluation of progress plan, modification of plan, replacing plan if necessary, terminating plan when conditions of problem have satisfied, storing plan, retrieving later. Tests usually inaccurately test executive functioning because tests do only assess one step of all steps involved in executive functioning
Explain the vector analysis approach to determine ecological validity of test data
What are important predictors in predicting future job succes following mild TBI?
