Yes, so we agree on the first. Nice!
and in this case it was the 'seminary student' who was in the right.
Acts 22:3 (KJV) I am verily a man which am a Jew, born in Tarsus, a city in Cilicia, yet brought up in this city at the feet of Gamaliel, and taught according to the perfect manner of the law of the fathers, and was zealous toward God, as ye all are this day.
and for a little preemptive work...
Philippians 3:5-8 (KJV) Circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, an Hebrew of the Hebrews; as touching the law, a Pharisee; Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless. But what things were gain to me, those I counted loss for Christ. Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ,
let's take this a step further...
Matthew 5:20 (KJV) For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
Paul knew and explained that better way quite well.
But now I disagree on the second point you seem to be making; that Paul being a 'seminary student' prior to his conversion was some great advantage.
No Paul being a 'seminary student' prior to his conversion was a disadvantage.

Acts 28:23-27
New International Version
23 They arranged to meet Paul on a certain day, and came in even larger numbers to the place where he was staying. He witnessed to them from morning till evening, explaining about the kingdom of God, and from the Law of Moses and from the Prophets he tried to persuade them about Jesus. 24 Some were convinced by what he said, but others would not believe. 25 They disagreed among themselves and began to leave after Paul had made this final statement: “The Holy Spirit spoke the truth to your ancestors when he said through Isaiah the prophet:
26 “‘Go to this people and say,
“You will be ever hearing but never understanding;
you will be ever seeing but never perceiving.”
27 For this people’s heart has become calloused;
they hardly hear with their ears,
and they have closed their eyes.
Otherwise they might see with their eyes,
hear with their ears,
understand with their hearts
and turn, and I would heal them.’
28 “Therefore I want you to know that God’s salvation has been sent to the Gentiles, and they will listen!”
-----------------------------------------------------------------
Paul was in great error for he persecuted the church with all that learned knowledge'. Once Paul learned the real truth, all that man-made knowledge he had he counted as "dung" or "garbage". Christ was everything. Paul learned everything through revelation from One Teacher Jesus Christ.
The seminary people like to tell us how important it was for Paul to be a learned man, and a formally trained man prior to coming to Christ. They again manipulate the truth to justify their existence. See in scripture Paul did not learn from any man. His formal training was an impediment to his conversion or to the truth he obtained afterward. But God being who he is was able to convert even the most zealous and most Pharisaical person that there was: Paul.
Galatians 1:11-17
11 I want you to know, brothers and sisters, that the gospel I preached is not of human origin. 12 I did not receive it from any man, nor was I taught it; rather, I received it by revelation from Jesus Christ.
13 For you have heard of my previous way of life in Judaism, how intensely I persecuted the church of God and tried to destroy it. 14 I was advancing in Judaism beyond many of my own age among my people and was extremely zealous for the traditions of my fathers. 15 But when God, who set me apart from my mother’s womb and called me by his grace, was pleased 16 to reveal his Son in me so that I might preach him among the Gentiles, my immediate response was not to consult any human being. 17 I did not go up to Jerusalem to see those who were apostles before I was, but I went into Arabia. Later I returned to Damascus.
18 Then after three years, I went up to Jerusalem to get acquainted with Cephas (Peter) and stayed with him fifteen days. 19 I saw none of the other apostles—only James, the Lord’s brother. 20 I assure you before God that what I am writing you is no lie.
21 Then I went to Syria and Cilicia. 22 I was personally unknown to the churches of Judea that are in Christ. 23 They only heard the report: “The man who formerly persecuted us is now preaching the faith he once tried to destroy.” 24 And they praised God because of me.
Paul clearly states that man-made teachings led him in opposition to God. Christ alone was his teacher.
