Verb conjugation of "squat" in English

As I have already mentioned in my last email, it is a breakthrough, I have never been so successful. I have visited several Spanish schools and would like to discuss that by telephone with you.
We have learned that some tenses, such as Present Tense are easier and not as complex as others. Is that right? In my opinion, tenses in English are much easier than in the Spanish language.
Now I am learning by other means, such as reading and writing. I can not begin with conjugation training because I lack the basic knowledge. How are you learning at this site and which is your best lesson?
