I find the school system in the USA very interesting. This is the first time I have heard of Community Colleges, public schools and universities yes, but not Community Colleges. Here in the UK we have different schools, and these generally depend on the political history of the county or local area. Some counties have grammar schools, entry to which is dependent on passing an examination. Those who fail or who don’t take the exam go to other state schools. Or, if the parents can afford it, their children attend public schools – these are fee paying and not at all like the public schools in the USA.
Once in college hard work is essential. It helps of course if the course is interesting. My favourite subject at school was history. We studied the medieval period when knights went into battle attired in suits of armour. I had a big picture on my wall of a knight in armour with his shield decorated with a coat of arms. The weight of carrying all that armour, the shield, and his weapons must have taken a lot of his strength and not left much over to actually fight!
Whichever system you attend: a Community College or university; work hard. The effort you devote to your studies then will pay dividends later in life.
