Thanks for your input guys, taking all your replies into account i just spent two hours switching from heel to toe and toe to heel.. on both the practice slope then on the main slope. Im nearly there now but my instructor didnt sign me off fully because i wasnt turning from the top of the hill, just need to relax and try not to think too hard about what im doing and just letting it happen. Its a shame i hit that block last week otherwise i would have completed everything today and been ready to go without instruction but the important thing is that i have made good progress this week where as last week i made very little.
Once again thanks for your tips they really helped me progress and gave me a positive attitude that i had the power of a little extra knowledge. Passed level 4 just need to do main slope ready lesson which is turning from the top of the main slope and not waiting till half way down hehe
