6th form is much more relaxed as opposed to school. Although college is that bit more relaxed, you still get a lot more independence in 6th form and tend to be treated more like an adult by teachers. In that respect, there’s not an awful lot of pressure or stress.
I did get homework, but often you find that some teachers are more strict than others – that just depends upon luck, I guess. You get free time and free periods, and, depending on the school rules, can go home once lessons are over etc. Exam pressure just depends really on the way you go about things.
You can either spread it out and party/work systematically throughout the two years... as some of my friends did. Or, you can use my method and just do no work the first year, then end up doing 2 years’ worth in one.
Either way, it’s not constant stress.
