best prep tool for score range of 550-630

Magoosh is a good tool for GMAT aspirants, quant questions are very useful to students, In GMAT real exam I got some questions same as in magoosh quant. coming to verbal section this section is a quite different from math’s, It requires complete knowledge of English along with lots of patience to read passages. I felt magoosh passages are a bit lengthier than GMAT orginal exam.
Positives:
• Great flexibility to practice questions as we like,
• Magoosh score predictor is very accurate.
• Explanation of questions and their answers is very nice.
• Customer service is good, reply for doubts will be addressed soon.
• Magoosh YouTube videos like Tuesdays with Kevin are very useful.

Considerations: The only thing I feel wrong with Magoosh is the slow pace of English lessons.
