2 ways to get this done:
a) load form3, hide it and pass values directly to form 3 objects using a syntax:

Form3.textbox1.value = Me.textbox3.value

. This might require some more changes on the modifier's property of your controls.
b) create variables to hold the data and populate form3 when you load it. These variables can't be declared using Dim, but using Friend or Public. This will make the vars visible to all your forms. Then on Form3 load populate the fields with the appropriate var value.

With Form1
            TextBox1.Text = CStr(.ID)
            TextBox2.Text = CStr(.sname)
            TextBox3.Text = CStr(.course1)
            TextBox4.Text = CStr(.year1)
        End With
        With Form2
            TextBox5.Text = CStr(.address)
            TextBox6.Text = CStr(.contact)
            TextBox7.Text = CStr(.age)
            TextBox8.Text = CStr(.d)
        End With

i tried the second option but got stock at Form2 i cant load it in form3 .. but form1 loads..... i also tried the 1st option.. :) but no luck.. i still lack knowledge about that syntax... i cant make it work..

Startup Form:

Friend varID as string = "" 
Friend varSname as string = "" 
Friend varCourse1 as string = "" 
Friend varYear1 as string = "" 
Friend varAddress as string = "" 
Friend varContact as string = "" 
Friend varAge as string = "" 
Friend varD as string = ""

On form1's submit or next or whatever event you find appropriate

varID =id.text 
varSname = sname.text 
varCourse1 = course1.text
varYear1 = year1.text

On form2 submit or next or whatever event you find appropriate

varAddress = address.text
varContact = contact.text
varAge = age.text
varD = d.text

On the 3rd form load event:

Textbox1.text = varID
Textbox2.text = varSname
Textbox3.text = varCourse1
Textbox4.text = varYear1
Textbox5.text = varAddress 
Textbox6.text = varContact
Textbox7.text = varAge
Textbox8.text = varD

PS: If you allow edits in Form3, you can use the same code to reset the values in the textboxes - as long as you don't change the variables.

If you want to show form1 and form2 input values in form3 then drag and drop 2 new label in form3 and follow this syntax

Public Class Form3
    Inherits System.Windows.Forms.Form

    Dim ID2, sname1, course2, year2 As String


    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        End
    End Sub



    Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim Obj As New Form1
        Obj.ID1 = ID2
        ID2 = TextBox1.Text
        'drag a new label from toolbar
         label1.text=form1.textbox1.text
        ' drag one more label
          label2.text=form2.textbox2.text
    End Sub
End Class
