Which is the valid syntax of this query in MySQL?
SELECT * FROM courses WHERE (now() + 2 hours) > start_time
note: start_time is a field of courses table

This will also work
SELECT NAME
FROM GEO_LOCATION
WHERE MODIFY_ON BETWEEN SYSDATE() - INTERVAL 2 HOUR AND SYSDATE()

The DATE_ADD() function will do the trick. (You can also use the ADDTIME() function if you're running at least v4.1.1.)
For your query, this would be:
SELECT *
FROM courses
WHERE DATE_ADD(now(), INTERVAL 2 HOUR) > start_time
Or,
SELECT *
FROM courses
WHERE ADDTIME(now(), '02:00:00') > start_time

SELECT *
FROM courses
WHERE DATE_ADD(NOW(), INTERVAL 2 HOUR) > start_time
See Date and Time Functions for other date/time manipulation.
