Answer 1

Your code requires 2 small changes.
Change 1:
WebElement loc=driver.findElement(By.className("input1"));
is pointing to three Web-elements on the page, Instead use below
WebElement loc=driver.findElement(By.xpath("//input[#class='input1' and #name='pin_no']"));
Change 2: Its a Text field, so Instead of
a.moveToElement(loc)
Use
a.click(loc)
So you code should be as below :
public static void main(String[] args) {
WebDriver driver=new FirefoxDriver();
driver.get("http://fleet.idrivesafely.com");
driver.manage().window().maximize();
driver.findElement(By.linkText("Student Login")).click();
WebElement loc=driver.findElement(By.xpath("//input[#class='input1' and #name='pin_no']"));
Actions a= new Actions(driver);
a.click(loc).keyDown(Keys.SHIFT).sendKeys("wel").keyUp(Keys.SHIFT).sendKeys("co").keyDown(Keys.SHIFT).sendKeys("me").perform();
