i wanted to do my graduation make up. is it possible to learn it in a week?

i have make up here at home (my mom's), i dont want to pay big money, and i thought that since i could paint, maybe it shouldnt be too hard? IDK THO LOL. when i put on make up, i just put concealer, mascara, fix my eyebrows, blush, and lips. but thing is, it looks like i have nothing on. i just look cleaner. i dont want full glam, ive tried before at a salon and it doesnt look good on me. i just want a soft glam that still looks like i have make up on and i wonder if i could easily learn that?
