Please Need Advice

So, I recently took the Series 7 exam and got 71%. I was very devistated, I know missed by 2 questions.

Now I have one final try otherwise my job is on line. I wanted to ask, I have kaplan review and test questions were nothing like how it was on the test.

I wanted to ask what would be a better study material. I dont think I want to buy the book because I would not have time to study the material and confuse myself from Kaplan to new material. I was thinking maybe online lecture and questions bank.

I was debating between Training Consultants and Test Teachers online. Can somebody please help me asap.
