Compare each cell in two rows, but with an exception - google-sheets

Question

I have a table that keeps track of scores from a test. It compares the row with someone's answers to the row with the correct data:
A B C D E
+--------------+-----+-----+-----+-------+
1 | | Q1 | Q2 | Q3 | Score |
+--------------+-----+-----+-----+-------+
2 | Answers | C | B | A | |
+--------------+-----+-----+-----+-------+
3 | George | C | A | B | 1 |
4 | Judith | C | C | A | 2 |
5 | James | A | B | C | 1 |
+--------------+-----+-----+-----+-------+
The formula behind the Score column is:
=arrayformula(sumproduct(($B$2:$D$2=B3:D3)))
The first part of sumproduct is a static reference to the Answers row. The second part is comparing it against the row it's on. However I want to add an exception: if the Answers row contains an asterisk it should consider all answers correct:
A B C D E
+--------------+-----+-----+-----+-------+
1 | | Q1 | Q2 | Q3 | Score |
+--------------+-----+-----+-----+-------+
2 | Answers | C | * | A | |
+--------------+-----+-----+-----+-------+
3 | George | C | A | B | 2 |
4 | Judith | C | C | A | 3 |
5 | James | A | B | C | 1 |
+--------------+-----+-----+-----+-------+
How would I be able to do this?

Answer 1

Please try:
=arrayformula(sumproduct(($B$2:$D$2=B3:D3)+($B$2:$D$2="*")))

Answer 2

=IF(OR($B$2=B3, $B$2="*"), 1, )+
IF(OR($C$2=C3, $C$2="*"), 1, )+
IF(OR($D$2=D3, $D$2="*"), 1, )
this will cover up to 51 questions (columns / range of B:AZ)
