ahh i see, that's quite hard when they don't respond back @Blackcloud!
so firstly, it's a bit tricky to predict how your subject will go mainly because different courses/subjects focus on different parts of psych. for example, my uni had about 10-20 psych subjects to choose from (i did 10 of them in my psych degree) - and some were statistics heavy, some had a small section of stats and others had no stats! so it definitely varies. usually for first year psych subjects / 'level 1' psych, the theory and concepts are the main focus and the stats part isn't too heavy. most psych subjects start with learning classical conditioning (pavlov's dog case study) and operant conditioning which can take some time to understand, but once you understand it and practice some questions applying the knowledge, i think you'll be good to go!
the stats stuff comes under 'research methods'. the first part of research methods usually involves exploring research design, (i.e. qualitative vs quantitative study), how they collect date (i.e. types of measurements), then analysing the data (learning about standard deviation, null hypothesis, probability, etc) and interpreting the results. it sounds like a LOT right now, but usually these are things you learn over 2-3 years so i think your subject will only cover a small part of it in the first unit, maybe the research design part. if you have more questions, feel free to let me know!!
