i'm currently in MyEdSpace's Summer School and, so far, it's pretty good. i'll be learning the curriculum for my GCSEs this year, so it's good to get ahead and understand things a lot better! obviously, it's way cheaper than the average tutor. i think it's £5 an hour, and, as there are two lessons for each subject a week, that's £10 for every subject you do. but, my mum made me take them all since, apparently, it's way cheaper.
they give you multiple choice homework to complete with homework solutions and they walk us through the process of answering exam-style questions with a workbook that's easily accessible and downloadable!
however, I do think that a con of MyEdSpace is the chat and how many people are on each lesson. the teachers don't do it on purpose, but it can be easy to be ignored when you want to ask a question, because (from my experience) people talk off-topic ALL the time and fill up the chat with random nonsense (they can be put on timeout by some of the moderators tho).
i do think you can thrive by yourself by watching certain YouTube channels, like Cognito etc, and, whatever you choose to do, i'm hoping that you can pull off the grades you want at the end of the day.
good luck!
