A large gap between verbal and non-verbal scores on an Standard IQ test can indicate Non-Verbal Learning disability. It means that you are a strong verbal learner. Having the large gap can mean that you are sometimes "out of sync" finding some tasks easy while others frustratingly difficult.
The person who administered your test should be able to interpret the scores for you. IQ tests detect learning issues.
Here are web sites that I have found very useful for researching learning disabilities:
