It is interesting because I went through this exact question recently with an intern. My condensed advice is: 1. Are you still making progress? Keep going. Don't give up. 2. Are you spinning your wheels? Take a step back, re-evaluate what you know, investigate things you are not clear on. 3. Still stuck? Ask for help. Don't panic or be ashamed. Show the progress you've made in step 1 and share the things you studied in step 2.
