I am giving EDEXCEL for the first time and privately

Please guide me. I am giving EDEXCEL for the first time and privately, A level. Psychology, religious studies, English lang and litt combo, and sociology.

I don't have anyone to guide me at the moment, and I am not sure I will find anyone near me for the next 2 months.

The subjects I want to give will be in the UK system. I am not in the UK, I will be giving my exams from the Middle East. I have found some study material, but if anyone can give me more good sources, I will be very thankful

My biggest questions;

How difficult do you think my combos are?

Where do you find free course materials?

Are there any specific practical or coursework requirements for my subjects (Psychology, Law, Sociology, English, Religious Studies) that are difficult for private candidates to arrange?

 If a specific English or Religious Studies syllabus has a Non-Examined Assessment (NEA) component, how to get it marked

Is there a specific order I should study the topics in to build a good foundation? For example, should I start with one subject first

? I am also not sure what papers I should be giving, like P1, P2, or p3 for each subject, i want able to understand very much on the website. I want to give only A level

Thank you. Please be nice and guiding. If you don't have any guidance or answers, please scroll away
