I did my stage 2 3 months ago on Wednesday! It wasn't too bad in all honesty! I did use a couple of tools i found online to prep for it but it all seemed okay except 1 thing i failed on! This was the fixed wing assignment which i just couldn't get my mind around at first, Im retaking it in 2 days time but i understand how to do it a little more now. One thing i would recommend doing is checking what the ADAPT test is like on Youtube, its quite complicated and involved a lot of multi tasking
