Classical and acoustic guitar - be the best player you can be.
It's really all about placement tests. When you apply to a conservatory, they really have no idea to what level you've studied theory, harmony/voice leading, ear training/sightsinging, dictation, analysis, and most importantly, how advanced (or not) your playing level is.
On the day of your scheduled audition jury, you'll be rigorously tested in all these areas. If you've taken music history, ths may also apply to your transfer credits. The tests are not easy, and both these and your jury are usually highly competive and stressful, so you'll have to take into account that your nerves may lower your scores a bit.
While you might do well in some tests, you might score measurably lower in others. The results will indicate and what levels you will begin and your choice of school, which may or may not affect how many years you must attend to earn the degree program you are applying for.
It may help you to obtain practice tests to prepare, and/or get a little tutoring to see where you're at. :-)
Good luck!
