Do you write your exams in cursive or print?Watch this thread
My primary school forced everyone to use cursive. As soon as I left I realised that I no longer need to use it. I switched and never returned to that terrible form of handwriting.
Speed and legibility is largely practice. I found some of my old school exercise books recently and it's scary how much worse my writing is now that I basically never have to handwrite so that anyone else can read it. Everything I do these days that's for anyone else to read is typed.
I would always recommend only writing on every other line as well (especially for long answers). Improves legibility and gives you the space to add in an extra point/sentence at the appropriate point if you spot something you missed when reading through your answers.
