Top Tips
Practice but not too much: If you need to improve a technique, don't keep redoing a piece of work until it's perfect. Simply keep the mistake and annotate as needing improvement. Tell the examiner you understand the mistake and want to improve it NEXT TIME.Then, use the same technique for another different piece of work. This way, you don't have to keep redoing work that doesn't have the results you expected but you can still get better at it.
Don't miss out on marks: If you have any loose pages or extra writing but don't want to stick them over other work, hole punch them and tie them in using ribbon or string and the rings from the sketchbook. That way you don't have to throw marks away.
Keep mistakes: Much like the two tips above, you don't want to unnecessarily discard marks
Be tidy: As long as your work is chronological order, it doesn't matter how expressive you are with presentation but make sure the examiner can read your work. If you know your writing is messy, type up work and stick it in.
Don't cheat: As with all coursework, it's possible to get someone else to type it or draw it. However, it will be hard to consistently do this as the teacher will see your own Art style in lessons and everyone has different writing styles as well. Just use the checklists and you'll include all you need for the grade you deserve.
Have confidence in your own work: Don't compare sketchbooks with peers. Everyone has their own style and work pace. Just do the best you can, that way you don't need to feel stressed.
Ask for help: If you do feel too uncomfortable to ask for opinions on your work, at least ask for a decent copy of your exam board's mark scheme so you know exactly what you're working towards on your own instead.
Manage time: Forward thinking and planning will make your Art experience more enjoyable and give you time to fully extend your ideas Tip: Only do the required work set each week (and make sure to complete it), don't try to get ahead and start too many pages. If you do start too much, you may not have time to finish them before the end of the course. The examiners mark for quality and development (journey), not quantity. If you want to add more to each page later, tie some extra work into the sketchbook with string. Be concise and include both well planned and spontaneous pieces that tick each exam objective but don't go overboard.
Don't think of the whole project, just do the set tasks one at a time to avoid panicking.45 hours worth of coursework over two years averages out at less than 24h a year!
