Short of that, pick teachers in classes where you have participated a lot. If the teacher notices you positively, they will reflect that in their recommendations. If you do any extra-curricular activities (sports, clubs, band, theater, etc), the teachers that run those are great sources, because they’ve seen you working outside of the classroom environment too and will often include that information.

If so, then go up and ask them how they think you’d do at such and such school…or with such and such a major. Or ask them to help you decide between majors. If they say positive things about your abilities, then you know what things they’ll focus on if they write a recommendation. If you go that route, be sure to be really nice and thankful towards them.

People are almost ALWAYS nicer to those that are nice to them.

If you don’t get the warm and fuzzies from them, best not to ask for their recommendation.

By the way, did the teacher give you good grades? It’s funny how some tests and such can be individually “curved” to benefit the teacher’s pets….

I would just reflect on your relationship with this teacher. If everything has been positive between the two of you and you were able to maintain good grades I definitely would doubt a recommendation being written. Good Luck.
