Getting your insulin dosages worked out is an on-going process, and is different for everyone. You may be honeymooning, which can be a phase where your body is making some, little or no insulin, and may vary day to day. Do you have a doctor or CDE to communicate with while at college ?
The best advice is to read one or both of the books Using Insulin, by John Walsh, or Think Like a Pancreas by Gary Scheiner. Gary Scheiner has a good website with some of the same information in his book and some on-line 'courses'. (integrateddiabetes.com)
Make your changes gradual. Many folks split their long acting (Lantus) into 2 doses, one in morning, one at night. You determine the right dose by fasting for 6-8 hours to see if the dose is right. Once you have the basal (long acting / Lantus ) worked out, then you can work on the Carb ratio for meals and correction factor. This is covered in detail in the books, along with how to adjust for exercise, sick days, and other situations.
Try not to think of your numbers as 'good' or 'bad', but instead being within range, and if not, what adjustments might be needed. You will learn what an amazing job a normal pancreas does, and how difficult it is to mimic it perfectly.
