Will I face issues re-entering Thailand on a Tourist Visa after multiple prior entries?

Would like to hear from anybody who's been through this:

1 started the year on a nonB

2 school year ended, so I re-entered on a 60day Visa Exemption, plus did 30day extension

3 had to reenter on 60day Visa Exemption again to start at next school; by the time I found a decent teaching position, not enough time to process nonB paperwork so I left Thailand

4 want to come back for the second semester, but need to reenter on Tourist Visa which employer will use to have chance to process nonB

I already have been approved for the Tourist Visa, but will I have a problem re-entering, especially by land?

Last time I left, officer said no more re-entering til next year, but you have to in order to do your fingerprints etc

Hope somebody has some insight
