How to create a tech savy ad when you're not tech savy? Did I even spell savy right?

So i'm at uni for my one and only class this semester 'Advertising, copy and Image' But how am I supposed to come up with an ad as virtually appealing as my other class mates who have done similar prepatory subjects and who know how to use programs I can't even get access to? I'm not sure they should have put me in this subject first up! But aside from this frustration I am loving being back at uni and learning new things. Advertising is really fun for me as I love being creative with media. Only problem is I have all these fantastic ideas in my head but i don't have the skills to get them out on a page! Will get there!!
