They are good for GCSE but they don't offer past papers and they don't offer A Level. My son has joined Livemaths.co.uk for his A Level exams and loves them. They are similar to Conquer but a lot more friendly and when he wanted further explanation he just emailed them and they chatted using MSN. They are starting GCSE and KS3 from September and I will be signing my daughter up for it then. They are a lot cheaper than Conquer but they offer a lot more. Check them out.
