hello, I am a student currently enrolled as a sophomore in high school. I am puerto rican and currently learning the Spanish language. (didn't learn it as a child)

after I am finish with the Spanish language, I am planning to learn some of the Slavic languages; eg. Russian, Ukrainian, Polish etc. I am very good at learning languages, I started learning Spanish a year and I am almost completed with it. Do you think it would be very difficult for me to learn these languages? Do you think I should learn these languages?

Spanish was once a subject in Philippine schools but lately it was removed. Is it an advantage to learn this language? Is it more difficult than English?

I’m in high school in the United States and I would really like to spend next summer studying Spanish abroad. I assume a Spanish language school would be best? Does anyone know off-hand any good places for me to go that wouldn't cost thousands of dollars?

I don't know if I wrote the sentences correctly but,

1. Conozco a Isabel es simpatica.

2. Quiero conocer al hermano bastante bien.

3. Yo sé esquiar bastante bien.

Can you tell me if I'm using saber or conocer correctly.
Thanks in advance !

Im just not getting spanish at all i have all a's and b's but a d in spanish i need some tips on studying and some help please i would really appreciate the help
