Hi Alexiaponas.
I'm so glad to hear that you liked the TTP Verbal Course. We put a lot into making it a complete, effective tool for achieving whatever verbal score someone wants to achieve.
Now, going forward, whatever verbal practice questions you use, to develop stronger verbal skills, be sure to carefully analyze every verbal question choice by choice and fully define what makes the incorrect choices incorrect and the correct answers correct.
In other words, don't just shoot for the correct answers to verbal questions. You goal when practicing should be understanding each choice as if each choice were itself a question.
Also, get used to being self aware regarding whether you have really understood each choice and have strong, clear reasons for choosing the choice that you are choosing.
The skills of fully seeing what's going on in the choices and being clear regarding whether you have found strong, clear reasons for choosing a choice are key to scoring high in GMAT verbal.
