Well, for me to learn two languages at the same time I don't think it would be a big problem. Howevr, it might be for others. I studied two languages at the same time in high school and while it was quite normal for me, there were other students that were making one sentence using both languages. I couldn't understand why, but I guess it's different for each person. I'd say give it a try because if you don't you won't know what your abilites are.
