I find the course useful for the following reasons:
1) Clear explanation of the basic concepts, followed by practice on sample questions; this helps to reinforce the fundamentals.
2) Mock tests and homework – in my opinion, practice is very important! As for the mock tests, they build up my confidence as I see my score improving with each mock test.
3) GMAT Tricks and Traps help me to identify the answer efficiently and void the common pitfalls.
I am glad that I attended this course and achieved my desired score on the first try.
