Ok Let Me Review It: Jot Index Cards

Ok so you are probably thinking "really you are going to review index cards, aren't they all the same?" Well that is what I use to think until I got these.
Now a while back, you may remember that I talked about learning a new language with a program called Duolingo, and well I wanted some index cards to make flash cards.
I have to be honest, these are not very good. They are not very thick, and if you are writing with ink or a Sharpie it bleeds through. They will work for what I want them for, however, I wish that they didnt allow my Sharpie pen to bleed through. But they would be good for printing recipes on, or something like that. But if you are using them for flash cards, like I am, then dont hold them up to a light source (otherwise you'll see the answer.)
On a scale of 1 to 10 with 1 being horrible and 10 being great, I would rate these at maybe a 4.
