Compare two sheets and copy match value to new sheet

Hi,

I am new to macros and am trying to solve a problem where I have some data in sheet1 and sheet2.
Data on Sheet1 is as follows:
#Unit test Maths History Science
1 70 55 95
2 60 64 52
3 50 85 33
4 75 60 62
5 65 70 94
6 40 55 86
7 70 58 41
8 40 60 99

Data on Sheet2 is as follows:
ID #Unit test
1231 1 Maths History Science
1232 3 History Science
1233 5 Science Maths
1234 5 History Maths
1235 2 Science
1236 7 History
1237 8 Maths Science

I want to compare data of sheet2 with sheet1 such that #Unit test for each ID is identified and is looked up in sheet1. Further, subjects of respective ID is identified from Sheet2 is identified and looked up in sheet1. Subjects value from Sheet1 is copied to sheet3 along with ID and #Unit test. Sheet3 should look like:
ID #Unit test Maths History Science
1231 1 70 55 95
1232 3 85 33
1233 5 65 94
1234 5 65 70
1235 2 52
1236 7 58
1237 8 40 99

Any help on this will be highly appreciated.

Thanks.
