engine/gearbox noises

i've got a 2001 polo 1.0, i've just recently passed my test so i wouldn't say I'm the worlds best driver as of yet, if i come round a corner in too high of a gear when trying to pull away (before reolising I'm in a high gear) it jumps as expected but a loud crunching noise comes from the front end of the car, i've grown out of this habit now but was just wondering if the crunching noise was anything to worry about or if it is just to be expected?
