First of all, it shall not be tenable to offer it for tax under section 44AD. Intent of law is to benefit the business class and exclude service/professional class. Even if you use section 44AD this could be a matter of litigation at later stages and chances would be ruling with the intention of the law.
Now showing it as income from other sources or PGBP, it depends on the nature and scale of business. If the coaching receipts are substantial and there are seperate expenses like staffing, coaching premises rentals, computers, etc, then it shall be appropriate to show it under PGBP.On the contrary if the scale is small and there no substantial expenses relating to that, offer it as income from other sources.
I hope it helps to some extent.
